I support it but I was thinking of a roulette for every alliance raid.

A level 50 alliance roulette, a level 60, 70, and then an 80 when we get more of the Nier series introduced. The higher the level raid, the more the reward.

A Crystal Tower roulette, Void Ark roulette, Ivalice roulette, Nier roulette.

Of course they would come with their own ilevel requirements.

This can even be applied to the normal raid roulette as well since the rewards for that are pretty lacking currently.
