the game cannot be balanced because there are too many champions ...
it's near to impossible to balance the game while there are more than 150 champions ...
how is that even suppose to happen?
X champion is broken against A,B,C,D,E champion
while A champion is broken against B,C,D
while B champion is broken in compination with D
while D champion is bad without C
the game cannot be balanced , there are too many combinations to be considered ...
the actual reason why there are so many champions is not to make the game more fun and more active ... But so riot can make skins , wards , icons etc.. to gain money and put another stone to the unbalance foundations of the game pretty much the majority of champions are alike to other champions
there are 22 unique champions (teemo,azir and some others) that their abilities show nothing common to other champions ...
