I can't really say much for Simian Thrash since I don't have it yet, but I evade so often I don't think it would bother me. Then again, I solo alot. If I'm in a party (which I really haven't done yet), I would probably have my skills set up for behind attacks. I'm use to spamming Jarring Strike and Haymaker with each miss (most of the time I can get both in for 1 miss). I don't use Victimize that much unless I'm with someone else and can spare the TP.

Guess I'll find out once I get Simian Thrash though, so my opinion may change.
