treasure chest

treasure chest start to be so expensive, that i dont want buy it any more, i was lvl 59 it was cost epic 150.000 & blessed 75.000, now i lvl 60 it cost 180.000 and 90.000

but i still get 25.000 gold from win, so i must win 6 times to buy 1 epic chest? and it gives not so big rewards, after update it start to give items instead ambrosia which is not enough, when you want travel from one side map to other.
