So its pretty obvious that revenge gear is pretty broken at the moment, regularly triggering revenge mode in one vs one situations.

Rather than nerfing it, I say we should make it MORE effective on a per hit/block basis. HOWEVER, make it so that revenge ONLY builds up on an EXTERNAL block or hit. That way in a one vs one you will never see revenge mode, which is at it should be. however if someone else jumps in on the attack revenge will build quickly and let you tip the scales.
