Please don't do this to Pyke. I'm finally getting some enjoyment out of this game via mid pyke, and the current changes as of 6-14-19 will push him completely out of solo laning.
If you need to nerf his wave clear furthur, go ahead. But these changes completely take his wave clear away. He has none with them. You are forced to slow push a lane with tiamat and low attack speed.
I dont mind him getting nerfed, that's not my issue. If you wanna reduce his solo damage, mobility, cc, wave clear, etc. I dont care, go for it. But completely taking away the option to even pick him for a solo lane is a mistake in my opinion.
