A training-mode could help with the grind
Often when a training mode is brought up people think about bot matches.
But what if it were a training mode catered to the specific killers that let you earn BP. Like Nurse could train to blink to marked locations, whether set or popping up, and the closer you are the more points you get? Deathslinger, Huntress, Trickster etc could have target practice, Billy, Blight and bubba could have an obstacle course to go through etc.
All wielding BP in the end

A farming mode
Two birds one stone, I'd say: reduce the grind and improve your skills
A bot mode similar to the bot matches in the tutorial would be a godsend.
