Can't deny a ring to a bride though xD
Picking Doran's Ring isn't even greedy, it's just plain bad because the gold and damage from Spellthiefs is a hundred times better than the extra AP from the Ring.
Let's not forget the original AP "support".

I mean if your support doesn't enjoy doesn't enjoy free money and a cool movement speed passive that you can't find anywhere else that's on them.

I know this is a meme XD but almost every morgana will go
