A small thought - spirit disciple

Perhaps making some % of attacks ethereal would be a nice little nudge for spirit disciple as part of the vampiric buffs.

It always seemed weird to me that reavers, who can wield giant 2-handers and whatnot, can bypass all armor 50% of the time.. whereas a spirit disciple, with faster-and-less-powerful attacks, just has the one punch every minute, and the rest go against armor as normal.. kinda always seemed like the two oughta be swapped if anything!

It would be interesting if spirit disciple had 100% of the time ethereal attacks, some ability to activate that anyway. Plus a way to turn that off.

And a group buff that gives a spirit resistance from an aura, could be useful..

I wouldn't take Ethereal Blade from reaver (swapping them as you suggested), otherwise Reaver would be useless.
