Well i felt fine with clumping Kog'Maw together with Anivia and Fiddle because he built ap, which i was emphasizing on, and Kog'Maw's usual playstyle is AP/AD + Madreds, and his playstyle usually includes autoattacking when W is on, and using E and R to nuke, all from a distance. It's very nuke like behaviour, with the exception a ap-empowered auto attack. I guess AP-DPS would fit him best, but you have to consider It wasn't my main focus.

About tanks: I don't necessarily count tanks by how well they take damage, but, like you said, by their ability to initiate, and most of all, mess with the enemy team while protecting your carry and nuker as well as he can. In that way, i don't feel it's necessary to pick one of the main tanks, you can pick any hero that chan: save your team, initiate without dying, and annoy the enemies. But most times people pick squishy RDPS and squishy nukes these days, or bulky characters that take damage well, but can't protect your team or initiate well (Mundo is not a tank).

I strongly feel that such a player is needed.
