Fantastic tip bro. And what do I do if I want to play a Jungler? Or just don't want to be forced to play a long range mage because I never liked them before?
People don't like this preseason because it made certain characters FAR too opressive, and it was obvious they woudld be far too opressive, but hey, can't know for sure intill it's unleashed on the playerbase, right? I hav had two, TWO whole Normal games without Graves on the enemy team. Won one, lost one. But I lost every time when I had to deal with an ADC whose Q deals more base DMG than Veigar's W, and whose AA's deal double DMG to Melee champs trying to fight him.
Then we see some nerfs on the PBE and it reduces his 480 Q to be 430 or something. it isn't a fun time for anyone but the Graves player. Of course, other people may be luckier, but for me this patch has made me feel like I was being punished in several ways (less gold for the jungle, ADCs early game is now stronger so they aren't as easy a gank, item costs up, etc, etc), all to the howls of ADC's "Junglers had their meta! You can't complain." etc, etc.
I gues you should blame the unhappiness with this patch by the factthat ot everyone can play an ADC, so they end up having less fun (mages feeling they are cheated out by ADCs nuking harder and STILL rightclicking good, as well as the increased item prices, supports not liking the ward timers increase and top laners not liking having to deal with Yasuo and Trynd outsustaining them due to their nutty synergies with a mastery).
tl;dr when you clearly buff only a SINGLE subset of the playerbase and everyone else gets nothing or ends up being outright WORSE, it's expected there will be backlash, and no amount of "It's preseason guise!" will change it. After all, for all we know, most of these changes are here to stay.
Also, how on earth is this preseason as remotely as bad as Preseason 5? Only people complaining there were freshly minted junglers about how they keep dying after their 3rd camp, and the subset of "I want my paultry Dragon gold!" as far as I remember...
or burst 
(And the mastery for ap is actually not as bad as people say)
