Over the last year, I've played Warhammer: Age of Reckoning and Age of Conan.
I really feel sorry for both of them.
The bar's a bit higher now. The sheer variety of quest types now in WoW is just ludicrous. They put in a medevac quest.
Just mull over that a second. A fantasy MMO with a medevac quest. Fly in, pick up people in a siege zone, and fly them out.
And yes, it was awesome.
Quest lines where they basically give you invincible superpowers just so you can see the lore happen. The implementation of phasing really made me feel like I was part of what was going on and I was changing things in the game.
This is such a huge turnaround for Blizzard, who put all of the big lore-presentation bosses at the back of huge hardcore instances for so long. If you quest up through the game, you'll see Arthas, the Lich King, at least 4 times, and each time he's doing *something* that directly impacts *you*.
The shortfalls, however.
Crafting, except for jewelcrafting, is completely borked. Jewelcrafting has a lot of great self-buffs and very powerful things that can only be used by jewelcrafters. Other professions have very little, and my blacksmith has no reason to level over 415 (out of 450) in that skill.
Wintergrasp (the world pvp zone) needs some help. In order to balance the force, if one side is vastly outnumbered they get a stacking buff to their hit points, damage, and healing to compensate. This really means that the alliance on my server are basically fighting 10-man raid boss-level horde in PvP. It's not fun. They really need to fix the factions so we can temporarily swap to the other side or something. The horde is not much of a horde when they're outnumbered 10-1.
Certain class balance issues are still present, but not extreme. Warlocks are still an extremely fussy class to play, as opposed to other classes that rotate abilities or chain chance-on-hit abilities into combos, Warlocks basically stare at a set of timers and recast spells on a non-fixed rotation. Not fun.
All in all, they far exceeded my high expectations, for everything from content quality to quality of service. The servers haven't been perfect, but they also weren't the utter crapfest they were when Burning Crusade launched.
