I enjoyed my Warrior, but I'm really much more a caster sorta guy, and in WoW have a hard time choosing between Mage and Warlock. Heck, every class feels like a hybrid to me, even the Warrior for a time. But the Mage and Warlock abilities offer me options I like the most, particularly when complemented with Herbalism and Alchemy.
Casters do have a no-mana, equipment dependant damage source (wands) and there are casting focuses on gear, but it's pretty un-impressive so far. Which might be a good thing, gear inflation does it's own damage to a game.
In my experience, Wands sorta sucked. The only time they're useful is when the player blew through their mana. Wand DPS is not really much different from good spell DPS, given the level ratings on them. I would argue that a player has better DPS if they employ better mana management than they would if they just overnuked and then Wand'd the rest. This in both solo and group situations. Besides, in groups, overnuking just means a Priest has to waste mana on a class that shouldn't be drawing aggro anyway (though the PBAoE Root on the Mage and the Voidwalker on the Warlock are good defense against over aggroing.
But that's just been my experience. I haven't heard many casters bothering with Wands too much, but that could change if they started getting better
or if they started giving the caster an ability they didn't already have (like a Root for a Warlock or a nice debuff for the Mage).
Every character caps out levels, Talents, and equipment eventually. A Warrior's DPS is tied to their weaponry and Talent, as well as their ability to not die from holding aggro. But that's their role.
Every class can benefit from better stats though, or items that given secondary benefits. That doesn't make the Warrior unique in this regard, though I will agree they are the primary market for the "best" equipment.
Which is fine.
And what the ubers do really doesn't matter, except for those interested in being uber.
I'm actually having a hard time choosing my alt as a UD mage or warlock.
I've finally settled on a DoT/Curses heavy Warlock. We'll see if it's enjoyable.
