get a little sloppy when trying to avoid his ground pop up attack, you're going to get wrecked. Snooze a little bit when he's about to emerge from the sandfall, you're gonna get wrecked.
Screamer pods, known in previous games as sonic bombs, can put Diablos in a helpless state if fired while he's digging. This does not work when he's enraged, however, so they aren't an instant-win button.
I guess I've also learned that putting damage on vulnerable areas consistently is how you win fights. If you're not stacking multiple hits against their weak points, they won't ever get stunned. If they don't ever get stunned, you never really get the chance to go ham on them. Trading a couple hits here and there is fine for weapon resource building but you always have to be working toward that knock down and the big combo if you want to beat the tough monsters. Little else will do, at least for melee.
This goes double when hunting with just one other person. Monster health and stagger thresholds (how much damage you have to do to a part before they flinch) scales to something between 2.2x and 2.6x when you have at least one other person, making fights with two hunters extremely dependent on how well you can both lay down the damage. If you dabble in the multiplayer, I highly suggest avoiding duo hunts and trying to get at least three people.
He gets why the game is good but can't escape the impression that monster fights are time consuming and you don't have great feedback that you're doing damage or making progress.
This is actually one of the reasons I went back to older MH games after playing World for around 100 hours (that's not much; for reference, I played 4 Ultimate for around 300 hours and I'm still playing Generations (Ultimate), sitting at around the same amount of time). I play for the multiplayer, and in World's multiplayer, monsters simply don't stagger reliably. In older titles, landing something like a level 3 greatsword charge slash staggered monsters very consistently, meaning you could put your neck on the line, challenge the monster at a risky time, and be rewarded for your bravery and good timing. In World going for the true charged slash when the monster is still capable of attacking feels like a waste of time because they almost never flinch. In multiplayer, anyway. Singleplayer is still okay, but again, not why I play the game.
Sorry about the rant, just felt like giving feedback. I absolutely recommend going back and trying either 4U or Generations Ultimate after having your fill of World, if you can get your hands on them. They're old, they're clunky, they're pretty grindy, but the combat is so satisfying when it clicks.
the moments where the AI is like "I'm gonna fuck ya" really get under his skin.
I won't deny that these moments exist, but if they're happening consistently enough to get him carted (fainted, killed, whatever term ya'll use), I guarantee it's because he's getting greedy. Monster Hunter is not the kind of game where you can attack attack attack and then just press the dodge button when an attack comes in and get away. This ain't no Bayonetta. When you attack, you dedicate yourself to that attack, come what may. Until he understands that and starts to respect the monster instead of thinking he's an invincible super-soldier, he's gonna have a bad time.
Question: I just unlocked the Melding lady. On the surface it seems like a very easy way to get what you want versus growing or harvesting it. Yet in all the tips videos I've watched, not one person has mentioned her. Is melding a bad deal resource wise or.....? Because being able to turn 40 Monster Bone S in to Flash Pods seems pretty amazing. There's a lot of garbage in game you eventually won't need anymore (I think I'v got like 40 Great Jagras manes) and the Melder seems like a great way to turn it all in to something useful. A lot of noise was made about Zenni in tips videos, how the cash requirements go way up in High Rank. So far that doesn't seem to be the case in low rank. Does it make more sense to sell everything later on, rather than meld it in to something useful?
Melding is great, but its usefulness is limited once you're at the point in the game where you've farmed basically everything you need and you only have to check in occasionally to keep your potion stock up. It's certainly used, but in the late game, you're more likely to see someone going to the melder to get a monster gem RNG refuses to cough up than to make more flash pods.
