I've never actually played passion on USKO.... i hear it is starting to become popular now? why?
Is there a "cooldown" for skills such as Pain killer, blaze killer, return to life? that would be the only reason i would consider passion..... if there was no cooldown. then it'd be basically a warrior with minor heal combo
but, if there is a cooldown.... it would be a bit difficult, but if the cooldown is fast - still manageable as a "minor heal" combo so-long as they can be used simultaneously.
