Also another change I would propose is making it so that taratzu's proc doesn't mess up taratzu's spell. Since the back is on a 15 min timer now, my perseverance is completely useless. If I'm using my vah every 15 min when taratzu's procs its starts cool down on pants, so my pants clicky is never up. Same goes for a paladin, if he procs taratzu's, his spell will not cast even though spell gem is not grey'd out.
Edit - adding
I would propose making vah back proc a heal equivilant to healing value of taratzu's that way it doesn't interfere. Otherwise perseverence is useless 90% of the time if you got vah back.
