I no longer feel so much pressure. I don't feel the need to raid, the need to PvP, the need to do BGs and dailies and rep grinds. It's quite a relief. It's not that I'm lazy, I just don't care enough. What's the payoff? Gear, well I suppose pixels are nice, but I like fun. If something isn't fun, or at least helping my friends have fun, I won't do it.
Don't get me wrong, I'm not going to be bad. I'm not going to switch to one of those retarded "I want to do everything and fail at it" builds. I see no point to intentionally gimping myself. I'll still theorycraft and argue about lore and whine about class balance. I'd be missing some of the fun of the game if I didn't.
A few weeks ago I started leveling a warrior. He's about halfway to 48 now and I'm having a blast. I like leveling. I go at my own pace, by the time I'm sick of an instance a new one is in my level range. There are quests all over. I've ended up skipping about half the zones because I keep leveling past them. But what's the worry? Now I have places for more alts.
I'm really looking forward to the 50+ old-world content. Blackrock Depths is going to be so fun. Then I can run around the Plaguelands doing the badass Argent Dawn quests. I don't know what I'll do at 70. Maybe try some tanking. I know I'm not going to be tanking like my paladin, but I am convinced that it's a myth spread by bad warriors that they can't hold aggro on multiple targets.
