Balancing the game for Worlds
Here's what I don't agree with - surely Riot's intentional World balancing patch is artificially changing the game for the World stage? It is not a true reflection on how the game is played on the pro scene the rest of the year. It's like soccer changing rules just for the World cup where you can have 12 players on the field or handballs are allowed, but only then.
It doesn't make any sense, and Riot are open about patching the game just for Worlds. Clearly, even having to do this in the first place is an admission that something isn't quite right because they have to pretend the game is setup differently to how it actually is.
A lovely side effect of this is that the rest of us (99.9%) have to play a stupidly balanced game for weeks / months. I bet, most ironically, half of these overbuffed champions aren't even played in Worlds anyway.
