When the expansion drops can we please have a vender in the first city in Ishgard that sells a ring headgear that gives a 50% bonus to any class thats 30 and below? When people return to the game everyone is going to want jump on the expansion asap, and no one is going to want to level cross classes from level 1 to 30+.
