I think part of the problem is its not very intuitive for finding which are the main battles. We have a list full of battles, but most aren't in the same league as 1 or 2 with 100+ people signing up. They shouldn't even be listed in the same area on the site. The active battles with lots of joiners should be in a special area on the site by themselves
Also having to click on a separate "roster" tab is pretty clumsy for finding if its active or not. Should be more clear how many people signed up before clicking there
