Saving BPS for double bloodpoint events isn't extra beneficial.
I saved a bunch up to use to level Demo and the new survivors quickly, as well as level up Killers to learn their perks. People are saying, "don't use anymore you should save them for the double BP event."
You guys understand the bonus is additive right, using BPS on top of double event doesn't give you 4x it still only gives 3x the points. You could make the case people are more open to farming or playing chill during the event, but if anything people seem to be MORE toxic. Constant SWF using BNP to end the game in 3 minutes and killers tunneling with Moris, playing their strongest addon combos.
