overloaded champions are not ok

i don't get why riot say that they like being strong when they are good or they get picked every match and are a permaban in the lcs while other champions are left in the trash(overloaded kit) riot this is pure favoritism plus overloaded champions are cancer because they delete at least 10 champions of their same class except the one that can compete with him and most of the time that one is nerfed really hard
