With the upcoming F7 Remake it'd be nice to see a Fate event like when they did Lightning's.
Maybe they could make it so every class gets some style of Clouds buster sword as a reward.

Dark, Warrior, Samurai get classic Buster Sword (FF7 style)
Paladin, RDM get the Advent Children style sword.
Dragoons get the Advent Children style sword with a long handle so its like a lance.
Ninja gets both but smaller.
Mages and healers get an energy staff while the classic FF7 sword perminately rests on their back.
Monks get energy around their fist while the Advent Children sword stays on their back.
Summoner, the card user class have a broken FF7 sword style.
Gunner class has an energy gun while the FF7 sword rest ontheir back.

And with the actual weapons are equip the level three Limit Break is changed to Omnislash for every class, healer, DPS, and tank alike.
