Realistically, will warriors be able to hold aggro at all?

[Jimjam]

Another consideration is 1hs had better ratio in vanilla than 1hb.

Warriors won't be using 5:10 ratio weapons to compete with monk 6:10 ratio!

On a by swing basis warriors will generate more aggro than rogues and monks due to the aforementionds preference for piercing and blunts(!).

Also note warriors get their melee akills earlier, so they tend to produce more swings than other classes.

Some high aggro spells may be problematic, but wizards, enchanters, necromancers paladins and even clerics can root (in addition to those mentioned by op). Mage pets can follow an almost similar role?

As a warrior you want to fight a rooted mob, then when you see a tash, mal, slow land then hit taunt to piggyback off that aggro boost and hope that taunt aucceeds before root fails.
