I can tell you from my experience( i have a hero PP 3 months now) that it is quite difficult to be killed, especially with a nuke on the weapon!!11 PP can pown all nuckers, supporters, warriors, rogues and SOME tanks. The only way to kill him is: Silence and fear (if u are nucker) or pre-frenzy(if u are titan). Also it is difficult for PPs to kick eva's templars and paladins.
