'traditional' supports usually have CC and/or a steroid of some sort for their team in their kit. Most mid champs are more about self preservation which doesn't help their carry much if he/she is in a tight spot. This 'new thing' just takes time to get used to which is why mage-supports seem so strong. People where dying left and right to Annie but once people got used to her in a "I see you got Annie, here meet my chain stun Leona and die" kind of way the field leveled out again.

Before someone brings up support-mages like Lux and Orianna, they've always had 'Support' in their list of roles and were intended to be playable in the botlane, which they were.
