I'm rather impressed someone bothers himself to get these few guns he has to repair then anyway.
What? No he doesn't have to repair it, since Enclave drops mostly 40-80% condition avengers, which is perfectly sufficient for common pvp. I once farmed 14% minigun from Unity and managed to kill quite a lot of people with it before I died.
EDIT: Back to the topic
Enclave soldiers already have at least 2 times iron grip perk, it's almost impossible to drop their weapon using a sniper or laser. You need silent death and better critical, because it gives you +10 to roll so it is like 30% chance for dropping a weapon. I am pretty sure this gets nerfed at some point, well I don't mind it if avenger becomes a very rare weapon, but I doubt it. People will always find some ways to get it (dynamite, c4, one-hex critburst etc.) if this
feature stops working. I wouldn't play my 3xbrd bg after that, obviously.
