Whats your take on unusual Supports?

For me personally play much rather with normal supports like Naut or Karma but im fine with unusual supports when I Get behind the idea of that champ on support. For example I can get the idea of a Lissandra support for example because she has a lot of cc. But I really hate it when someone picks something like a Chogath or Nasus supp. These types of champs needs gold, minions or kills to be usefull.
