if this game truly was "perfectly balanced"
how would you go about making decisions that involves picking your team? If everything the same would you just pick whatever?
how would you decide what to ban? (obviously pros would still target ban)
If A=B, does that mean each and every single game is based around what 1st pick feels like playing that day?
would be a melee carry that can replace an adc (hint: it's already possible), picked against immobile teams, AND if his team has tanks and ccs
picked against immobile bruisers that can't catch her
generalist=can be first picked
damage amp=teamfight guy
global pressure=picked if you want to win by 20 min with an early game comp
picked to help juggernauts
mobile zhonya=lul assassins
living shield against champions like miss fortune and twitch
the true anti-mage
if riot makes his W not a joke, he would be picked to help a heavy AA team like with
or 
and I'd still ban
simply because I don't want to see him.
