I tend to look at AT suggestions with a skeptical eye.  
 
	 
 
	Basically, if the AT suggestion can be accomplished with a group of powersets added to an existing AT, id suggest that instead.  Example adding assault sets to a Sents vs making Defense/Assault ATs
 
	 
 
	If just adding additional customization / pools / epics would work then id suggest that over groups of powersets ... 
 
	 
 
	And so on.  
 
	 
 
	A new AT should be the last option IMO, we have a lot already, and there's some balance tweaks in the works for those.
