Last pick say: I dont have any support champion, mid or afk.
Morgana is a good support, easy to play and only 1350. If you really don't want to spend ip, just get kayle or nunu. Taric and janna are cheap too. If you're going to use the same excuse, don't play ranked then, its that simple.
BUT DONT DO THIS "mid or feed" SHIT. THE FIRST PICK WILL BE AN ASSHOLE AND LOCK MID ANYWAY, SO I HAVE TO LEAVE THE STUPID CHAMPION SELECT AND LOOSE LP, UNLESS I WANNA PLAY 4vs5 OR WITH A DUO MID.
