This topic may have popped up before, but since Mirage is on the brink of being released it seems like a good time to bring up the possibility of adding more school insignia gear.
School-themed gear has always been the most common and loved style for wizards since Krok and Mooshu. Since it's such a popular style, why not add mirage-themed school insignia gear? This could be dropped from the final dungeon or one-shot gauntlets in the future. Many wizards would spend the time to farm dungeons for this.
After looking at the new faction gear from Mirage, it seems underwhelming in comparison to the grinding necessary for the badges you need to buy the gear. The gear is also purely cosmetic, which means that the only incentive to buy the gear would be if it looked remarkably different and better than the current Mirage gear. Adding school insignias on this gear would be a definite incentive for wizards to grind for the badges.
