For Victimize, I think the 60 sec recast is fine. In the past I used to spam the hell out of it. The increased recast now forces me to utilize other PGL abilities, and fights have been just as fun. At least they increased the accuracy on Victimize. I hated having to equip Hawk's Eye or Still Precision to even out my luck.

I can't speak on Simian Thrash since I haven't reached that ability yet.
