It's not even the stun duration nerf, that was a good call by rito. But the ult nerf.... really? He cannot even stand a chance against assassins since they can retaliate faster after he pushes them off of him. And it's because the slow doesn't last long enough anymore. He can't even stop runners with his ult anymore, since they just get away and you have just wasted your ult :(
Papa Palpatíne3 votesI feel it was too early to nerf or buff him. Should have waited a little while longer and see what the community was able to do to play him and counter him in builds, masteries, runes, etc.
Profirix3 votesI think this is the majority consensus on the side who was upset with the nerfs. There is also another train of people who are happy he got nerfed. Personally it was a little too early.
draakar3 votesBy nerfing him they've stopped most people from trying to learn him. Its like what they did with Illoai and we know what happened to her.
Milkydragon1 votesWell I learned him for sure, I have him 5, but now I have to relearn a bit because my old combo and zed counter doesn't work anymore
Rockm Sockm3 votesHe is basically a c/c bot until he gets RoA, Rylais and boots.
His stun travels about 2 feet if you dont move with it, making it only half useful retreating.
Zero in lane mobility to escape ganks. If you use your Q(or ult post six) to trade, you are a free kill.
He has a huge ass dead zone because you cant instantly activate Q to stay alive.
He is a niche pick that requires teamwork.
Zed went unnerfed an entire split and sol didnt last one patch?
I seriously can't believe it.
Now go loom at Tarics rework and go wtf.
Brahmsauce2 votesHe basically needs Rylais+RoA to become a real threat.. just delayed his power is all.
Profirix1 votesNaturally.
Venowolf1 votesNaturally 
is the guilty of his ult nerf...
Profirix1 votesI don't really think so. Most Aurelion's I've seen have gotten kills within the first few minutes of the game, before they could even get Rylais.
Br4ndon1 votesAt least theyre not buffing then scrambling to nerf 4 patches later.
Calabok1 votesGood nerf.
iPooUnicorns1 votesClassic Rito. Make a gimmick kit, let it be strong on release and then nerf it to shit tier next patch.
Profirix1 votesThats why you only buy new champs with IP :)
