1st of all, don't quit your warrior just yet. I was a mid level warrior in beta, but not as high as Whyteshadow. I admit, warriors are not as fun in the beggining levels as your shaman probable was, but they do get better. Your get some killer moves where you could easily kill a rogue. I beleive one of them attacked everytime they dodged and there was another one like this. As far as rage goes.... I was annoying, but the warrior is made to be like that. Blizzard realized that a warrior doesnt have mana, they have rage. To help you learn on rage building, look for some tips in warrior forum; a good way i know of, is to duel weild so you hit more, and if you can, tank for a bit, which you will tuant the mob anyways because of your damage. the challenge with the warrior is to generate and manage rage, once you figure this out, your warrior will be so much more fun. The warrior does good damage, and can take tons of damage back. You could easily kill more mobs with a warrior than with a rogue in less time ( considering downtime and at once). At least in my experience. Since you are a tuaren, then you could easily escape battles the way i did with my tuaren druid. warstop ---> run. warrior obviously wears the best armor.
Either way it is your choice,and now that the actual game is out and im seeing what rogues can do, im THINKING of making one.
A good class for you might be the druid or shaman imo.
Both can escape fights very well, and the shaman later on wears mail. Don;t forget you could heal in battle. If your a druid you could become a bear, which resently got their armor upgraded i beleive 360% from when in druid form; or you could become a cat which can stealth and attack fast like a rogue.
Again, it's still your choice.
And Whyteshadow, please try not to tell warriors to tank ( even though they should if they are the only able to ). in beta ( on my server) there used to be tons of warriors because blizzard said they would not make warriors a specific tanking class. Now this game is turning into FFXI where if your not perfect ( tanking warrior, or totem spamming shaman) groups dont like you much and would drop for the next person. So im a shaman until they switch up the warrior a bit, or i might make a rogue +)
