Lil edit: 6.6 mechanic

I think this will be unfair/boring for leaderboard gameplay. Now your gameplay will be random-based, because some bonuses obviously better then others (like, getting cores, in limited waves stages obtaining freezing tower effeciency, ect.). Make for everyone same seed also will be bad, because at some levels will have meta with x2 loot, other will be just boring (because same every time, and specific stat will be found fast by brootforce)

Maybe this will be good idea if it's will disable leaderboard, but it's still strange thing for ability and how it must work with "trigger random ability", and with 6.6.
