A suggestion for next years' preseason

Please don't make all of these changes at once. Like, you reworked 7 champions on a Yi-like scale, changing atleast 2 of their abilities completely, while also completely changing ADC itemization AND masteries AND the flow of the game with stronger minions and the rift herald and expect us to be able to play this? I'm sorry, but thats just too much. It already took me 3 games to understand Graves new abilities, but I have still no idea how to itemize and play during the different phases of the game. It will take me atleast another 7 games to get back to the knowledge I had of the previos Graves. That multiplied by 7 PLUS the other changes, it will take me surely over 100 games to somehow get back into this game, and that's too much. Please Rito, don't forget about your casual player base that have other things in mind than LoL. Games right now are just unfun because basically everything is broken and you lose with no chance of being able to adapt. Next year, make small changes over a greater period of time. That will help players learn and adapt.

One last thing: I'm not an expert, but how on earth could the crit keystone mastery pass PBE. It's hella broken... And why did anybody feel the need to rework EVERYTHING? I was kinda ok with how the game went in S5, no need to rework everything and basically make LoL a hell for the next month before everyone and everything will be nerfed again...
