Rather than derail threads on individual classes or specializations, I thought I would address some common questions or misperceptions in this one thread.
We don't consider "bloat" a bad word. Players typically say that when there are more talents than they can possibly get. That's the whole idea. When you run out of interesting talents, then that's when we think we have a problem.
Related, if we do our jobs right, you are going to run out of dps talents (or healing talents if you're a healer, or mitigation talents if you're a tank). We don't want every talent to feel mandatory since you are prohibited from getting them all. We want you to have choices.
We don't consider every talent that doesn't directly lead to higher dps to be a "PvP talent." Survivability is a big deal in Cataclysm. In that vein, talents that keep you alive (or help healers conserve mana) are indirectly dps talents.
Related, many trees lost a lot of true PvP talents, such as dispel resistance or mechanic duration reductions. These are the kind of talents I describe as "arms races," where you need a counter to the ability someone else is using to try to counter you. We'd rather reel the whole thing in a little and make things like crowd control or dispels as powerful or as weak as they need to be baseline rather than assuming you have talents that make them less powerful.
We are providing some damage talents for healers. For the most part, those are optional talents for leveling, soloing, PvP or times in dungeons or raids when you don't need to heal.
Likewise, we don't assume tanks need to pick up every single dps talent in order to generate sufficient threat. You'll likely need some threat talents, but since you're probably dipping into a dps tree to get some of those, you're going to find way more than you can afford.
In most cases, raid buff talents are cheap and often have selfish bonuses. If they lack a selfish bonus, it's because we consider the talent so compelling that you'd probably want it when solo anyway. We see a lot of "I'll skip that talent, because someone else will bring that buff," but obviously that logic starts to fail when everyone comes to that conclusion. Also make sure you're familiar with how some of the buffs and debuffs have changed for Cataclysm. We are trying to make it even easier to get the big ones, especially for 10-player raids.
We aren't designing PvP vs. PvE trees. Ultimately, we consider a talent specialization to be a stylistic choice. However, given the challenges of nailing both PvP and PvE balance, as a consolation prize it's nice when at least there are no dead trees. If Frost and Arms weren't raiding juggernauts, at least they did have a place in the game in Lich King. But Cataclysm represents an opportunity to try again, so we hope to see Arms and Frost raiding, and Fury and Fire in PvP.
We aren't overhauling every single class. We are changing paladins quite a bit, and the resource systems for hunters and warlocks and Balance druids have changed. I get the sense some of you are waiting for that magical build in which half of your talents have been scrapped in favor of new ones, and in many cases, those changes just aren't coming. That's not to say we're done with any tree.
We haven't been super concerned about numbers yet, and we aren't at all concerned about glyphs yet. It's helpful if you note abilities that seem to have lost a lot of damage compared to live, just so we can make sure it's intentional (as it is for many AE abilities). If you think you won't use some core spell just because it doesn't hit or heal for enough yet, then it's fine to bring that up, but you can also assume that the numbers just aren't quite right on it yet. Of course this also means that you may feel underpowered (or rarely overpowered, though players almost always feel underpowered) compared to someone else. This does not mean you're doomed in Cataclysm or that you need to SCREAM REAL LOUD to make sure the developers don't overlook it. Numbers are much easier to adjust once we're happy with the basic mechanics.
We've gotten a ton of great feedback already, and I want to personally thank you for that. We make changes every day that are the direct result of the feedback we receive, and that certainly includes this forum, the live forums, and many of the great websites out there were players discuss World of Warcraft design.
