I appreciate the interest!
My current "plans" for the scav mode itself was a more Idle mode for people to leave running and it slowly auto-loots. But I can be swayed in a different direction, I haven't made a decision on how to flesh out Scavs and it could involve a poll asking what you guys think at some point soon if I can't make a decision.
Adding Scav rep is definitely an interesting idea and I could see it adding an interesting level of depth to making decisions during events. e.g. you win blackjack against the drunk scav and you lose scav rep lol. Maybe good scav rep could make extraction blocked events lower chance of happening among other things potentially.
Definitely a great idea to consider more.
