I do not agree with that kind of a nerf simply because it won't do anything, literally anything. Botrk is the part of Zed's core build while Lee has SLOW in his kit so with or without reduced MS they will always be able to stick to you, not to mention that Yoummu's Ghostblade is also a part of Zed's core build. I am not a Lee Sin player so I won't talk about him as much as I am going to talk about Zed because Zed is one of my mains. As it comes to Zed's kit and mobility as a part of his kit, Zed is fine, everything about Zed's mobility, damage and utility is fine as it is, but there is only one thing that isn't right and that's his E. Why E? Answer is simple, his E is the spell with high AD scalings overall, but that should be changed because, that's the core spell for Zed's wave clear mid/late game so E's scalings should be separated somehow. Leave the PVP scalings on his E as it is now, but cut the AD scalings IN HALF against minions so he won't be able to push and clear as Xerath or Orianna. That change won't affect his assassination or dueling potential but it will affect his laning phase, his splitpush potential and his waveclear.
