Season 6 in a nutshell
Everyone is complaining that this season is the worst by far. Marksman are running a muck in lanes other than bot, especially Graves. Xin buffs, and a mini Zed ulty that brings back memories of DFG.
I, personally, am happy with the way league is going. I find it much more entertaining than Season 5 was. It adds diversity into the game. You never know what you're gonna be playing against anymore, and that's what Riot wanted. They didn't want the game to be predictable.
When I first started playing, I took Ashe top and it was amazing, especially since I was new. Then as Season 5 came to an end, I noticed a trend. I could be sitting in the loading screen and depict exactly where everyone is going. You have a tank top, tank or assassin in the jungle, the era of assassin's mid (as a mid mage main, i hated this), then you had your marksman and tanky support in the bot lane (or Soraka if you wanted to make people hate themselves). This became boring as I started playing against the same pool of about 15 champs every game. Now I load in and see 4 marksman and a tank on a team and it makes it interesting.
Yes, I have my bias towards this Season (please don't touch my Vel :c), but it's nothing that wont be realized and fixed by mid-season. When it comes down to it, a lot of the comps that are being played, can easily be countered if you play right. Since 6.3 came out a day ago, I've played against 3 Xin's and none of them were ever a problem. I've played against a Talon with the new Duskblade and I destroyed him in lane.
Not everyone will be made happy by every buff, nerf, or rework that Riot does. Any small change in base stats or scaling can literally make a champion impossible to play, or make it completely broken. It takes time to get these things set.
Basically, we're 2 months into a year long season, stop complaining already. It'll get fixed and things will change halfway through the year.
