i would like to suggest making RDM useful again. here are some ideas:

allow rdm (either through a JA or maybe just a spell) to cast its buffs on others. I dont see the balance issues of having a rdm being able to cast stoneskin/phalanx/temper/enspells/boosts etc other players, since sch or /sch can already do this.

give rdm debuffs that are unique to the job (and dont give them to all other jobs the following update hi2u break, addle), ex: magic dmg down, magic def down, a spell that annuls mobs ability to heal themselves, etc

for the melee enthusiasts out there ( surprised you still exist) a stance that increases melee output while draining mp (either a la souleater or just a mp- per tick)

that is my suggestion box!
