I feel like the one thing League can take from DOTA 2 for ranked is...
DISABLING CHAMPIONS THAT GOT REWORKED AND NEW CHAMPIONS IN RANKED FOR AT LEAST A WEEK Because it is triggering to see people call themselves "mains" of the new champion on the first dat, then feed This would also save a ban so we don't have to face/play with X new/reworked champion
and also the PBE isn't open to everyone
