Riot I'm not a Kog'Maw player but...
From the comments on your "rework reversion" post, it seems that there is a significant outcry for the ult to be reverted as well in order to bring back AP Kog'Maw. I dunno anything about it but apparently it was a lot of fun, and I think if League needs anything at this point in its life, it's more fun. Maybe listen on this one?
when his ult decimates you regardless of your health. Are you sure you want that?
