Riot, please read (about Lee Sin changes)
I'm a Lee Sin main, and seeing those changes left me speechless. At first when I heard he was getting a retune I thought, okay, it shouldn't be so bad, maybe they can make his early game a bit weaker but give him better damage or utility late game. But these changes looks like more of a nerf early game and not much in compensation.
I'm posting changes from the Megathread on /r/leagueoflegends because it is quite a good alternative to what you guys are planning.
"I feel Riot removed power from fun parts put them into unfun parts, that they try to force players into weird play patterns. Least fun ability of Lee Sin, his passive attack speed. You use the ability for energy regain mainly, and it's a forced on pattern that is not really enjoyable, feels more like necessary evil to slow you down a bit. Lee Sins E, is not overly fun either, but it adds heavy utility though. It is also kinda under appreciated how much you kill attack speed with it, but it's lots of power there. What is fun is using Lee Sins Q, W and R. His Q feels REALLY rewarding to hit, and should be biggest part of Lee Sins power budget, since it's his exciting power. Adding a cost to ward hop is OK, but it makes a much weaker Lee Sin late game. Making his R stronger when kicking INTO enemy team doesn't make sense. Main usage of Lee Sin kick is to kick people out of team, or to use as a powerful execute combo with his Q. Neither of those scenarios really is about kicking INTO enemy team. And those are the exciting parts of using his ultimate. My idea for change: I propose instead to lower his early game ratios make but make them stronger into the late game, don't move ALL ratio's from bonus AD to total AD. Make his Q and R bonus AD, and his E total AD. Why? Because this will preserve his nature of being fighter-assassin. Tank Lee focus more on E, and Assassin Lee more on Q-R. Try to maintain his duality, and focus on making the fun part of Lee fun. tl;dr; Remove power from boring parts of Lee Sin, not his fun parts." (Wertilq)
There you have it. I hope you guys see this and consider what Wertilq posted and be a bit more sensible in your nerfing.
