Koraa says that bloat is another term for "I can't have everything I want" and that Blizzard actually intends to make every class tree feel a little "bloated", forcing players to make tough yet interesting decisions regarding the talents they take and, ultimately, the talents they sacrifice. I said as much in a response to one reader, noting that talents look so good now that it's hard to ignore a lot of them.
This is actually a good thing. This allows for creative gameplay and diversity in builds... although of course, with millions of players looking to min/max, I have no doubt that there will eventually be cookie-cutter specs. If anything, it might be what Blizzard is trying to avoid. It would indeed be refreshing to see a little less homogeniety in viable specs in the game. Looking at the Wrath talent trees, do you think that they're bloated? Are there too many good talents to pass up on? In this case, I think, a little bloat is perfectly fine.
