Umm the bears are fugly, for one thing, and are big fuzzy tanks, for another. I'm not a boomkin because I want to look like a bear. -_-
I've been balance from day one (or whichever day I hit level ten and started getting talent points), and I've thoroughly enjoyed it so far.
If I did go feral (an idea that I've been toying with because of its acknowledged superiority for leveling), I'd be in Cat Form 24/7. Pretty, graceful, and kickass DPS.
Then again, I don't play WoW to powerlevel. I've been playing for nearly a year and have just hit level 66. I play for the social aspect, and because of how dynamic the world of Azeroth is. It's very interesting and a lot of fun. I spend a lot of time running around and exploring, or helping the lowbies in my guild, or manipulating the Auction House. Leveling gets Godawful boring after a while, which is why so many people quit playing. Grind grind grind, whack at everything, gather bullshit, etc.
Out of curiosity, do you have your Aquatic Form? I know so many druids who don't because the quests are such a hassle.
