So the new expansion and the urgings of a friend have made me do what I thought I'd never do.
I came back. Recovered my account and got a MoP ten day trial. My 80 death knight in heroic tier blues and purps was hijacked by Chinese gold farmers who vendored everything, geared him up in AH greens, and sent him out to farm elementium. I feel fucking violated, dude.
I started a new guy on a new server, an undead warlock.
My impressions of the current state:
Holy shit inflation, holy shit leveling curve. When I first started playing (Vanilla WoW) it took me a few weeks to get my first character to level 25, and I think I farmed my first actual gold coin around level 25. This guy I got to level 25 in like three hours, and had 130g. Low level mats were always expensive to take advantage of people powerleveling their professions, but with the leveling changes and heirlooms almost everyone does that shit. Individual scraps of linen cloth are going for more than a gold coin each on the AH. Don't bother with first aid, do RFC a couple times and AH your way to wealth.
If you've never played before you'll probably still take a while to get there just because you're getting your bearings and exploring, but if you know what you're doing you should be level 60 in less than a week, even playing casually.
They somehow managed to make low level BGs even worse. They've always been twink city, but it's pretty much impossible to make a meaningful impact on the game now without a full set of heirlooms, you will literally get one-shotted. Don't even bother.
Talent changes are the best thing to happen to WoW, fuck the haters:
If you haven't heard, talents were completely overhauled. Where previously there was a standard set of three talent trees like every other MMO, now you just pick a spec and it gives you a new set of abilities to go with your choice. I'm plaing a warlock so I'll give it in warlock terms. Demolocks get-- lol nevermind who gives a fuck about demo. Affliction locks get agony (which is no longer a curse, which means the other curses are actually useful now outside specific situations), unstable affliction, soul drain, and some other abilities based around dropping lots of dot shadow spells on the enemy. Just like old affliction warlocks, really. Destrolocks are awesome. You trade shadow bolt for incinerate and corruption for immolate, you get conflagrate and some other spells, and instead of soul gems you get burning embers which can be consumed to buff our spells. Also m'fuckin' chaos bolt.
Basically as far as specs go, there's no real meaningful difference between the old way and the new way. You still pick a spec and mostly stick with it (There were some hybrid builds before, but it's not a massive loss compared to what we've gained), you have fewer spells but all of them are useful and have very nice synergies going. You no longer have every actionbar filled to the brim with abilities, and your spellbook isn't clogged with 50 spells that aren't useful to your spec/aren't useful at all ever.
Instead of the old talent trees you have talent tiers that unlock every fifteen levels, with three choices in each tier. That was a little offputting at first, but it just means that instead of getting a tiny, barely noticeable (aside from a few disproportionately impactful exceptions like Nightfall or Felguard) boost every level, you get huge and important boosts every fifteen levels.
I actually love all the new changes and I'll definitely be subscribing once the trial runs out. WoW's a very old MMO and to me these changes have brought it back to 2013, cutting the fat out of the game and streamlining it.
My biggest complaint is that they've killed low level content even more. That's always been the case with the new expansions, but between heirlooms, faster leveling, and instant dungeon spam, there's no pretense left of things not just being a dead sprint to 85. And even that's not that terrible really. I mean, it's not like I'm jonesing to collect some boar tusks.
