Its been a while since I've played. What are the top ADC's and Supports nowadays?How long are we talking? It's been more or less the same (with the exception of Nunu(nerfed pretty hard recently)/Cait/Miss Fortune becoming very popular recently) since finals. Ezreal is still #1 probably. Corki has been seeing less and less play since S3 started (the trin force cost reduction might help).
No idea how far you're talking and I can only really talk about the last 5 or 6 months
