The claim that players would misuse BfB means this would be poor design seems to me to be a non sequitur. I could maybe agree if this was a class people begin the game with, but its not available until after they have completed a huge portion of content. Also, I disagree with you on tank design. If it can be implemented well I don't see any real reason a tank could not have an ability that caused extra damage to themselves if the reward for doing so were worth it. Cleric Stance lowers a healers ability to heal for the sake of damage. I totally agree with you about Provoke. That is why I suggested replacing MRD with LNC and not GLA. I do not think Keen Flurry alone is enough to subsidize the loss of Foresight. However, DRKs best damage mitigation is locked behind parry procs. Keen Flurry invariably means more up time for Reprisal. I have no clue whether or not this up time is a greater or lesser effect than that given by Foresight, but I think a case can be made that it might be.
