A Pattern I Often See In Yellow/Green Ranks
There'll be a few Survivors who don't have all Perks yet, mostly there's at least 1 with 2 not being rare either.
Anyway, match plays, yada yada.
Then on the scoreboard, i see that the ones with all max Perks and rare Items are also often the ones earning generally less BP.
What gives?

First, its very effective to do a gen alone, as the time you gain if more survivors work on one doesn´t get down proportionaly.
but doing a gen alone gives about half the points you get for doing a gen with someone else.
The same holds true for unhooking. its not efficient to have 3 players swarm the hook, so you better do gens. But unhooking a survivor nets you 1500 points in no time.
Basicly, some people sacrifice their own bloodpoint-gain for the sake of the team making it out.
Gotcha.
