Completely agreed, but it's hard to find players to group and throw about 5 games. It doesn't take long at all, but many players don't understand it's value and the long term benefits. They either get too impatient and only want to do it a few times, or they don't think it's important enough. so instead you are left to wait through many games as a peaceful antag, but this rewards even lower since the recent patch and it takes a lot of time.
But you MUST lower MMR to about 40 to 45 percent before you take on that BP mission to ensure success and to also yield larger rewards. ESPECIALLY if 1 or 2 members are going to be gimping themselves with Treasure Hunter weapons. The mission will NEED to be easier because they will be doing very little damage.
But, isn't it strange that we have to do this in the first place? How silly the whole situation is, players purposely having to throw games to lower their MMR in order to achieve greater progress in the long run. There's an unofficial META to getting BP and rewards, you can' simply trust the system and play the game normally and that's sad.
