Before you read my post, I'd like to note I play only as dual-LW (because I play with my girlfriend and we don't need any NPC meddling around).
Currently playing as a two-hander wielding dwarf (because Baruk Hazad y'all!), and I dunno why you bring up Enrage as a viable option. I only use it if I have been hasted by my companion prior to my turn AND at the same time have atleast three target for a whirlwind. Otherwise it's better just to hit 'em one more time actually, and have a 30%-smth chance of crit (at level 11) anyway.
And tbh, from a melee perspective, there is no point in having warfare higher than 4 for the skills (atleast at my level 11), as two-handed gives me damage AND crit multiplier.
