Again, I see no need for enduring. Does Invul have some kind of +end power? If SR gets to combine passives and get a Sent based +recovery, shouldn't Invul? Shouldn't Shield? Like SR, it doesn't get end recovery until the T9. Of course, Shield's T9 isn't a steaming pile of uselessness like Elude and Unstoppable.
 
	 
 
	I get what you're going for. I also get Troo's distaste for altering the set too much.
 
	 
 
	It's actually easier for me to make the argument that Bio and Rad armors provide far too much in the "extra" department, as do ALL of the Sentinel armors, and to perhaps nerf them all, rather than continuing down the road of power creep and making already godlike sets even godlier.
