Ask a Warrior Thread.

ACB hits 3 more monsters than CB and hits harder (while still being faster) though so that's only relevant for some of 60-100.

I'd mostly advise against Paladin because their specialty is 'elemental damage' and of late, that strictly means going up against extra resistances compared to other warriors. They do tank a bit better but don't have much DPS for endgame content which is already extremely dps-dependant more than anything else.

i only spoke in regards of 3rd job, since no warrior would use soul driver at all in 4th. im aware that 4th job acb is better than soul driver.

to be honest, soul driver isnt that good for any warrior, period. its mostly just the novelty of it, since Mihile Soul Driver isnt even Holy element. that is why i listed the FP and Shadower alternatives, in case he wanted a class that could use the UA skill optimally :x
