So, aside from the absolute nonsensical naming stuff (Turn-Drake? Really? Chaff-Repear? Howtf do you reap chaff? What does that even mean?) - his kit is ... weird.
The A1 and A2 are set up to be sorta damage-based in that they ignore DEF, but the rest of his kit is clearly not intended to be a nuker - so I guess the DEF ignore is just fluff? He hits harder than normal supports, which certainly isn't a *bad* thing, it's just ... misleading.
His actual kit is fairly strong - the question is whether he can actually do two jobs at once. Can you form a team where his kit allows you to essentially turn 3 champs into 2?
If, for you, the answer is yes, then he's great! Otherwise? Perhaps he'll end up in your vault.
