purpose of warrior

[mystang89]

First things first-this is not meant to troll. It's an honest question.

I've never played a warrior before so I really don't know what they are for and just have the examples I've grouped with.

From what I've seen they aren't really meant for taking because they can't hold aggro. They're aggro seems to be dependent on procs, which is iffy at best. They have taunt, which any tank knows only works when you don't need it to. Most of the time I group with a warrior who is supposed to be tanking a healer or caster will take aggro and I'll have to snap aggro back because the warrioris waiting on a proc. I'm a 45 ranger BTW just so you know where I'm coming from.

Now when a warrior gets hit I've noticed they can take a bunch of dmg but it's all up to rng. (not ranger, random).

The thing is, most of these warriors I've grouped with seen like good people who know their class and are trying. So is there something that I'm missing?
