Ever since 4.2 Rival Wings has been pretty dead, at least on Chaos DC. It's a shame because I think many would like to work on the achievement for the mount. Ain't happening and I don't think that will change until the next map is added. These are two simple suggestions that would improve the experience by that point.

1. Reduce the amount of people needed to get a match going.

Looking at how Frontline has the 72 and 24 people variants available to improve matchmaking, I think something similar should be added to Rival Wings as well. Correct me if I'm wrong but I believe Yoshi-P has stated that there are no plan on reducing the maximum amount of people in a Rival Wings match. Maybe not reducing the maximum amount but I think that instead of requiring teams to be maxed out each time, the amount needed to get a match going shouldn't be same. 32 people (4 light parties on each side) could be a solution. The remaining 16 could join in progress.

2. Add a daily rotation system when the second map gets added.

To ensure that Astragalos isn't completely dead by the time the second Rival Wings map is added, a rotation system should be implemented just like the Frontline system that is confirmed for 4.3.
