It makes no sense. I have to go out of my way not to be near an ally when he is facing someone because the minute i go near the target pops revenge. Its even worse for me since running around solo is disadvantageous in the first place. (Lawbringer)
Just because you think a fight as to be solved by rushing
If you blindly attack him, in a braindead onslaught of heavy attacks, then he will get revenge and possibly win. Play smart and even with the current revenge gear, you will have the advantage.
