Hullo, haven't really posted in a while.
Depending on the activity of the crucible it might seriously be good to consider an eternal polling system over the current polling system.
I've mentioned this before, but I don't think these temporary comparisons don't properly reflect the community's opinion on a card over more than a short period of time.
Particularly with the forum activity slipping, it might just be the current opinions of a handful of members that decide what goes on in the polls.
