Tank/Support Doram should still be viable - if only for healing RG full & 10% ATK/mATK buff.
DPS Dorams are still kinda bad
I wonder if the deff reduce skills will also reduce the new 2nd stat resists? (Nyang Grass)
But long story short: i'd love to support my guildmates while leveling with them.
<edit> As for Jobchange ... Event NPC for a few Job EXP would solve the "need to level job" after the update.
Sincerely
