I'd disagree that EGC is killer sided, aside from that specific situation it doesn't really favour any side, it just encourages people to leave rather than hold the game hostage which is a good thing for both the killer and any survivors who want to see what the killer was using.

I never really used endgame pig myself but I know a lot of the community who play her loved that style of play but now it's almost entirely gone because her traps are pointless after the last gen is completed.

My solution to this would be to have more methods of starting trap timers. The start of EGC should start the timer. Maybe also having healing/unhooking others start the altruistic survivor's timer (if they have a trap on their head).

One idea my friend and I joked about would be to bring the trap into the next game and pray you were going against a pig so you could remove it lol.
