Most buggy, unbalanced pos patch iv'e ever played, in the 3 nearly 4 years iv'e played this damn game.
Tanks are too tanky, while also being able to do damage, Supports either do more damage than their ADC in lane, or they shield them for 80% of their HP bar. Any mistake that support makes doesn't matter. If they get caught out, stunned, over step, doesn't matter, your support pressed E! HAZAAAAH
And, this is the absolute most hypocritical patch i have ever seen to date. Riot claims they want diversity, yet, what, only 3 maybe 4 ADC's are viable, maybe only 2-3 mid laners are viable. I'll admit, Jungle has some wiggle room. But Top is just like the others, where if you don't pick a heavy cc unkillable tank, your basically trolling.
Even with the new mastery/rune system coming, it is very clear, that some are WAY better than others already. So it'll be just like it is now, where everyone will only have 1-2 build paths that actually do something.
