With certain primaries it is the best choice of Melee classes for damage end game.   
 
	 
 
	The best version of KM, SJ, Staff, Electric and probably Savage  
 
	 
 
	Some Scrappers will do better with other primaries (MA, WM and EM for example).  Brutes will get more AOE with some primaries like MA, KAT, BS)  And of course some primaries are not available on Stalkers (TW, WM, SS, SM)    
 
	 
 
	I've found team survival to be excellent due to decreased threat.  Solo survival is good, but not as good as Scrappers or Brutes.  And Tankers of course have a completely different role.
