I didn't realise this was going to happen.
I thought they were going to address it by reducing player use instead of increasing NPC use....oh well...
Well, I remember Sarah saying that NPCs would start equipping them but they would not stack them the way that players do. So this whole spamming thing seems like an exaggeration in the first place. I have seen them use them but I haven't seen any Pythons chaining 5 SCBs.
