Alright, I typically do not do an update to this chart so soon after the last one, but I think I made a few mistakes in the last one that needed to be corrected. The biggest thing was that because of the increased number of viable supports and the addition of champions like Thresh and Nami, the format started to break a little bit as there became less and less overlap due to the higher increased number of possible counters. The whole point of this chart is for overlap so this was going against the goals I had in mind in creation. To fix these goals, and to fix the "where is zilean on the chart!?!" requests, I added a new section titled Unorthodox Supports. These have the typical counterpicks that I've asked people who specialize in this champion as well as what I've seen in my experience. This should keep overlap in the actual chart without leaving out some supports which people feel so endeared with.
As always, let me know what you think and you can follow me (or let me know) via facebook or twitter. And you can also check out an android phone app I made with some cool people: "Spellsy's Support Cards".
For a blog/facebook-special I have also released an alpha version of the description of each countermatchup in the chart from above, it is pre-release so it is not the best format, but here it is: https://docs.google.com/spreadsheet/pub?key=0AllLJAxUt7qcdEhWbnVfTEtZM0otdDd2R2pkTUJ1bGc&single=true&gid=0&output=html
Also, here is the new desktop version <coming soon>.
