Quite a few things wrong with the changes that riot has failed to really take into consideration.
They want games to end quicker yet did not do the following:
-Make dragon less of a late game thing
-Nerf Early game champs
-Buff Late game champs early game and make them less about late game and nerf their late game(they literally made kog maw so much more of a late game champ and trash early. which is why his WR is pathetic, just to use as an example)
-More onto the Kog Maw thing, if they didn't want games lasting long why in the world did they keep him as a late game champ while they were doing their ADC pass.
I am sure there are much more things that i missed but this is what came off the top of my head and quite honestly the first thing riot should of though of before even going forward with these changes.
In a nutshell, if you like these changes then most likely your main cast of champions got buffed. If they didnt they either make no impact on the game or actually causes your team to lose games.
