Once again, thanks a lot for all these translations, means a lot.

This caught my eye

・Tank 壁役
・Attacker　近接ダメージ役 (Close Range)
・Damage Dealer(Nuker)　遠距離ダメージ役（MAXダメージ）(Long Range)
・Healer/CCer　回復役（兼足止め役）
・Buffer/CCer 補助役（兼足止め役）
(He put the English himself so no need for me to translate here.)
Buffer/CC as a class/job function of its own, guess that means RDM and/or BRD, at least for starters.
I hope we get to see either soon, as I enjoy this type of party play.
