-Energy Charge and Full Power Charge are skills you have to do PQ's to learn. They take up slots, too. So it's a trade off. Then again, between Super Saiyan and Full Power Charge, I'm only using one actual damage skill at this point anyways. When shit is so inaccurate, and in everything but the most desperate fights I can Ultimate my leisure, it just kind of invalidates every other ability except strike attacks to add into combos.
-Online has the crippling deficiency of introducing load times just for the sake of connecting to leader boards and loading in people's characters. Compared to SP where there are zero load times (for me at least) and you're not left waiting, it's kind of irritating. Two, if you disconnect from the server (which is god knows where) it boots you back to the main screen, and that happened within like 2 minutes of me going online. Release week overload, or shaky connections to a server across the world? Hard to tell, I haven't been back online since. I haven't actually tried MP yet.
-I suspect the blocking situation is more about online play than VS the AI. I think the desire was to give people the option to stamina dump everything and to be able to eat shit loads of ki blasts, but not teleport or just block spam away people's combos. Basically, I think they included block because it's an expectation, but gimped it intentionally to drive the kind of online competition they want to see, which isn't turtling. Maybe there's a lot of subtlety in the back and forth between players who are carefully reserving their stamina for that critical teleport dodge. Unfortunately, on the SP side, someone forget to tell the AI that blocking isn't something that works well for players. Possibly to enhance the difficulty. Blocking in the game now has its place, but it's almost exclusively about ki blasts. I dunno. Blocking is just so shit it has to be intentional.
-For getting a roll on a guy...it's hard to tell if they play by the same stamina rules as players do. Guys definitely get guard broken. But like, Goku Kaioken x20? That motherfucker will use Spirit Explosion pretty much every 6 seconds, truncating how much you can DPS him, and there's no way in hell you're going to guard break him. I ended up using Super Vegeta to just Final Flash his ass back to the stone age, it was the only way to win the PQ with keeping someone at x health when Goku is beaten. And he could STILL block 70% of it sometimes, guard break and take a little damage, then dive right back into the fight full power. Wailing on him would have taken forever and spirit explosion (god I hate those abilities in the hands of the AI) will just chip away at your HP and the best you can do is teleport dodge it. And then he can just drop a Super Kamehameha on you, and take 60% of your health.
-So whether or not some guys are vulnerable to long combos is kind of a matter of two things: is the AI tooled up to block half your attacks, and do they have redonk amounts of stamina to block all day with no problems, or fire off those defensive AoEs? You get the most ki from taking damage, I think, so eventually you have to expect that after a certain number of attacks, even the weakest character using the best AI that has one of those attacks will use it as soon as they are able. So they kind of built in the systems for players to escape getting a train run on them by other players...and the AI mercilessly exploits that too.
-Anyways, I can usually get a good roll going on guys by exploiting the heavy attack part of a combo, which I don't charge, and it seems to give me a nice finisher kick or punch that sends guys flying. You Dragon Rush after them and weak attack into them while rushing, that engages another combo you can start, which you quickly dump a strike attack into, or a point blank ki blast. If that sends them flying, you follow up and do it all again. But against harder guys (basically starting in the Cell Saga) that stops cutting it. Some guys aren't paralyzed anymore while you're hitting them, so they attack you back in the middle of your combo and then do massive damage with one of their's. If you can dodge out of it and not end up back in it, you can usually execute on a combo or move in retaliation before the AI flips the "fuck you" switch again. Sometimes they'll go flying and you can bounce them around a bit, sometimes they aren't having any of it. PQs tend to have easier AIs and characters in them, they're not broken for dramatic effect....usually. But basically any time you're fighting a pissed off Saiyan or a villain of the series in an important moment, their AI is probably tweaked and they're doing something crazy like what I describe above with Goku. At that point it starts becoming all about Ki Blasts and Super Attacks that won't leave you sitting directly in front of the enemy so they can hand you your ass. You combo because you have to, to build some Ki and open them up for a finisher. But it's a losing proposition to actually stand and fight a lot of them, because they will block, if they even need to, and you will not. You also have to start relying on consumables to keep up (Vegeta's last mastery test was painful at like Lvl. 37) because one well executed combo or ultimate can put you in danger.
-Charge attacks aren't broken per se to me, the AI is just excellent at exploiting the wind up. They also only guard break. They do not send guys flying. They are essentially worthless vs the AI in my mind. Another thing for online players to strategize around, but does you dick in SP that I've seen so far. I expected them to work like in Budokai where you could kinda seamlessly layer them into combos. But no. I just mash buttons and know to mash the RMB when I want them to go away.
-I have not yet seen beam clashes. Beam attacks in general seem to travel fast so it's hard to react to them too. I know that "super fast melee exchanges" or "burst fighting" or whatever you call it are literally just an animation, the weaker character seems to take a smidgeon of damage, and both combatants get a couple bars of Ki instantly. (They're also invincible while it's happening and anyone that makes contact with the AoE of the struggle gets slapped.) So it wouldn't surprise me if Beam Clashes just aren't a thing that can happen. There's definitely power superiority rules. Like beams will pierce through burst ki attacks, and Vegeta's Big Bang will cut straight through Galick Gun. In general though, the positioning is so loose in XVABC123ICUP, and it's really de-emphasized cutscene wind ups to the attacks, that maybe they just thought people wouldn't be standing still long enough for it to happen. It's something that could be tested in MP.
-I also went Vegeta first, because he is the best. You can move on to other masters when you've completed his training. After him I went to Krillin just to get his training out of the way, and the difference between their styles is just hilarious. You need a A rating at least before Vegeta thinks you're even worth a shit. Krillin will "Good job!" you for a C, and kiss your ass starting at like A.
I'll be playing Friday night probably, I'll hop on if you want to give MP a whirl. Some of those PQs would be way, way easier to get a Z rating with another human player, instead of AI.
