Weekly challenges/quests
So it would be quite nice to have some form of weekly quests, similar to the daily ones. Basically 1-3 weekly quests that refresh every Sunday or so? They would give a higher blood point reward maybe even a really small amount of shards. Since daily challenges give like 30-60k BP I was thinking about at least 100-150k, probably even more.
You should have seperated ones for killer and survivor so you don't get unlucky and only get ones for the side you currently don't want to play.
As for the type of challenge, I think it should be something that makes you play at least 10 games, which I think is really doable for most people. And then just some rather easy to accomplish thing that just takes time like repair x amount of gens or hook x people and so on.
We could make it more ambitious and harder to accomplish but that's not really the goal, it should just reward you for playing the game for some time the current week without being to tedious or needing to go out of your way for something special without making it so you can just go afk for every game and still get the reward.
