Matches base on player power killing low tiers of arena and halts progressions in other aspects of the game.
eg. 415 player power (normal play, collecting food champs etc) = arena in any low tier chosing v hard opponerts
strip not used champs playe power drops to 375 = area opponets choice better matches
Current solution:
dont farm, dont pull any champs clear you champ roster to bare minmum = have some better chance to arena
four 4*1 champs = 6k player power
one 3*1 food champ = 2-3k player power
I think gold arena has better alghoritm as not take player power therefore allows accounts to progress
On extreme, leave only your arena champs and get rid of all other (as your arena team is mostly the best you still can do some dragon lvl13 and CP) this will rise your chances in b/s arena :)
Of course at some point player power will stop to be significat factor (ironicaly once you reach and stay on gold arena), but before that your account progress is extremly handicaped.
Or make vault to be vault = champs in vault are not added to your player power
