Pyke just looks like an assassin designed to be viable as a "support"
His whole kit just smells like an assassin, only his pull and ult are actually supportive. I can understand that you wanted to make an "aggressive" support, but making so that an assassin can be viable to lane with an ADC while having the possibility to get fed and make so that the ADC gets fed at the same time (thanks to shared kill bounty, a mechanic that shouldn't exist at all either I believe) isn't a great idea in my opinion. Everyone is complaining that there's way too much damage in the game, adding the possibility to have 2 carries at the same time in botlane without the drawback of lacking scaling/supportive abilities isn't what this game needed when you wanted to make an "aggressive support". His roaming-kind of gameplay is actually interesting for people who like this concept but who wouldn't play
because of his general design, but the fact that he roams not only for supporting another lane, but also to get himself fed (and regaining his lost health while returning to botlane because of his passive) is, well, cancerous. He looks fun and interesting, but I don't believe that he should've been released in this current full-burst meta.
Please, don't let him get the typical "newly released champion" treatment: even if his winrate is so-so as first, DONT BUFF HIM, his kit alone is more than enought to make him more than meta, don't do anything idiotic after release please
