This is probably going to wind up being a dumb, pointless thread, but maybe it'll surpass my low expectations. This is directed at the Council, and folks in the top 500 range (1800+ Elo and all that) -- that is, people who possess the experience, insight, and high-end play data to have this discussion (a group to which I obviously do not belong, but hey, I'm just asking the question).
What's a reasonably accurate champion tier list in the current version of LoL (v22.214.171.124, current as of December 17, 2009)?
Last I heard -- and this was a couple patches ago -- Cardmaster, Morgana, Corki, Malphite, Amumu, Nasus, and Soraka were popular bans in high-end draft tournaments, based on a very AoE/CC-dominant metagame. I suspect this has changed since then, and I wonder how the balance is currently staggered according to the experts.
Again, I'd prefer that the other plebs like me didn't chime in, as a tier list based on your personal/anecdotal experience is basically someone throwing darts at a board with no hard data or rationale to back it up ("Twitch and Yi are OP" doesn't count as rationale). But I know there will be a few of those replies anyway, so I hate you in advance.
EDIT: Top team compositions/synergies would be interesting points of discussion too.
