Give killers a BP multiplier for playing versus SWF (Please have a look)
Your queues are bad now, wait until ruin gets nerfed, so why not offer a BP multiplier as compensation to the people that are going to act as BP pinata until the game gets fixed?
How it works: If you play against a 4-stack, you basically get BBQ for free, if you play against two 2 stacks, same thing. If you play against one two stack, you get only two stacks of BBQ, if you catch my drift.
What does this do? It makes more people play killer, and it would allow for some killers to not use BBQ as much as they do now (which makes survivors happy because of the aura reading).
How can you go wrong with this? Please have a look at WGLF as well, it is pretty annoying to use it ATM, feels like a dead perk most of the time.
