Do NOT Nerf Pyke
I know the PBE changes were to nerf Pyke's solo lane potential (it does that quite well). The problem is that it makes Pyke's supporting worse than ever. At this point, they should just remove stab in general. If you take away the AOE part of the ability and the bonus damage it just becomes useless. Nerfing his E makes his support playstyle slower, which isn't ideal in a hyper-diving style champion. You can no longer help get backline minions low for your ADC when pushing or try and defend tower when your ADC is dead or backing. Riot probably made these changes with only top and mid in mind, but the damage on minions with his E and the AOE of his Q was really important to how you played him support. Instead of making him completely useless to get him out of mid and top, why not make cooldowns higher? Or rather make his E do less % damage to minions to stop his wave clear. That way he gets punished more for using his E or his Q to farm waves.
I know that a Rioter or at least someone who has contact with them will probably not see this. I just hope they take a deeper look into Pyke and realize killing his solo lane potential is NOT the way to go about this.
(Side Note)
Why is Riot trying to push its ideas on where someone should and should not be played? If it's too strong nerf it, but this takes it to the next level. Instead of trying to balance Pyke to not be super strong in Top and Mid they would rather just kill the playstyle off because it doesn't fit what they want for the champion.
Also, remember this video? https://www.youtube.com/watch?v=Mb53aa_nFTo Encouraging people to try new and weird stuff to see if it'll work.. Seems like people did that and Riot is just trying to shut it down.
