I will say this about the Current State of the Game
This is probably the most diverse the game has been in a very long time. You can play Mage's bot lane again, bruiser's, mages in the jungle, top lane is basically a free-for all. Jungle is kind of crappy right now but that's because riot won't nerf champions like Udyr, Trundle and Xin Zhao.
Like, i love the diversity since Marksmen finally got the boot they deserved buuuuut crit ADC's could use some tiny tweaks here and there to even them out along with On-Hit ADC's gettting a bit of a smack to put them back down(Looking at you Kai'sa, i know your dad was never around but someones gotta teach you how to behave.)
Oh not to mention that games are extremely snowbally nowadays, i hate that part, but i love the Diversity in all the lanes as of late. The snowballing seems like a pretty easy fix to me, tower's aren't strong enough, bot tower is still the weakest and once a lane starts steamrolling, it starts STEAMROLLING.
Hopefully riot gets to work on these issue's and keeps the good parts, not being forced to have atleast 2 marksmen on a team is actually a good thing in my opinion but the snowballing should stop.
