I think implementing this will solve a lot of the current complains most players have
1- people complain all the time about Seth farmers that buys from the market it would solve this
2- cheaters that transferred illuvials to side accounts
3- people who complain about DH points being too high and that it will rewards lucky players that dont invest time into the game
the multiplier shouldnt be too high
just a random example lets say every 100 hours play time you get +10%
a player with 1000 hours at the end of the season will have its points doubled, it doesnt sound too much for someone that invested 1k hours
