Thanks Byrth.

As far as an Ambush buff, It could be reworked to give the bonus as long as you're not tanking, similar to Conspirator. This way its universally good so long as you're not in a low-man situation... So on harder content!

However, they'd need to rework its actual effects as suggested here(?) to make it useful too...

at the same time I'm not sure what I'd give up for it. im at 5/5Feint 4/5assn-charge 1/5Aura Steal. I want Aura Steal, I'd Miss my ass Charge if i dropped it to 1/5....
