Ok, this might be a bit cray, but I got to thinking: current AI is really bad, so to account for that BSG just makes them ESP users with laser guns. This is no fun.
What if you could have a 3rd option when going into raid, and get to control a random rogue / raider / boss / boss guard? (Maybe it's just a 1 in X chance when going in as a scav.)
This option would not allow you to extract, you would not be able to pick up loot, you would just be there to PVP. I would envision PMC exp or after-raid random items given for the performance in raid.
Yes, it would be hard to implement, yes it would be hard to balance, yes there will probably be ways to abuse this (letting yourself get killed, hiding all raid, etc).
I think if the rewards vs time are good enough, and you set proper limits, it should be something that makes the game both less predictable, and more fun for engagements. It would also give new players a chance to practice PVP with good gear but no fear of losing it (since you can't take it with you anyway).
Thoughts?
