It's been a while since I did any content in this game with my tanks, but I remmeber this: Paladins are better at mitigation of damage thanks to Shield Oath and their rotation is really simple (spam the aggro rotation); Warriors have lots of health, they are better at handling groups of mobs, and they have two skill combos: the aggro one and the debuff one. You want to keep aggro, but you also want to keep Storm Path's debuff on the boss.
Their Defiance mechanic is also a pretty interesting thing once you get Infuriate (which gives you 5 stacks of Wrath instantly), but that's at level 50. Until then, you want to keep all those stacks with you. Actually, you want those stacks all the time after, too, but you can use Infuriate right after depleting your Wrath in any of the other Wrath-based skills (Unchained is pretty good for recovering aggro, for example).
I have no idea how Warriors work on the raiding scene, since I do not raid at all. But I think Marauders might be better suited for off-tanking. That lets them apply the debuffs from Storm's Eye/Path without having to worry about pulling aggro.
