I don't really have the funds to buy anyone costly right now, but I've got 2000 IP and want to unlock a permanent go-to support to play if we need one on the team. So here are my standard options according to the "support" checkbox in the shop:
-Soraka -Janna -Morgana -Talic -Teemo (never seen him as a support though...) -Zilean
If there are other support options for 450-1350 IP I'd love to consider them as well. Which of these tends to work really well as a support?
