Earn umy in the pvp season

I want to propose that even in the pvp season you can earn umy in the arena .... we leave the first 10 battles for free, and the cost of 5 umy per battle after the tenth, but with the possibility of winning 7 umy if the player wins, this can incentivize player to rank in the arena and improve in the game, the Umy earned can be used to rank again or to evolve karapets, many players do not earn enough umy to pay 5 umy per battle, so they play and sell, causing the drop of the value of umy, but if they can earn by winning, they will have more desire to try to rank up
