frontlines ?

[Teno]

Frontline does not need roulette to survive, but Rival Wing certainly can't survive even with Moogle Charm event.

Because rival wings might not be the most efficient way to get these tomestones (and the mode is more confusing than frontlines to some people), and people who do pvp might not even care about tomestones rewards to begin with. I'm convinced XP would be a bigger incentive.
