True.  But the thread subject was how unkillable can you get?  
 
	 
 
	Since Stone only has the one hole durability wise.  
 
	 
 
	======
 
	 
 
	For most content on most teams even Invul is overkill. 
 
	 
 
	My SR tanker only died twice, both times exemplared. (Stupid people and the Posi 1 steps) 
 
	 
 
	WP is basically unkillable even on minimal IOs once you get onto teams running multiple  maneuvers. 
 
	 
 
	Even Fire does great with a couple buffs.  On my SS/Fire brute I was annoyed I never died because my best attack was ROTP.
 
	 
 
	I imagine that is part of why BIO is so popular.  Its tough enough, and can be adjusted on the fly based on team configuration.
