Zilean seems to match a lot of your requirements for support

His CC is one of the strongest slows in the game, and it lasts 2.5 s at rank 1.

His ult is a game changer. The ability to bring an ally back from the dead (if you guess when they'll die) is unbelievably OP. There's an item that exists just to give you a similar ability on a massive CD. But Zilean can get his ult to a way low cooldown. Like, even so far as to use it 2x in the same fight.

It's hard to farm when the enemy has a very spammable spell with 700 range.

Weaknesses : not much in the way of traditional support stuff (no heal, no hard CC)

very squishy
