From my experiences (both endgame and general partying) Rdm has always been a support role, and otherwise "jack of all trades." The only thing Rdm specificly excels at is Debuffs/enfeebling, second is enhancing, 3rd is their melee skills (which really isn't that good compared to real melee jobs), and just gets lower from there.

My biggest issue is the fact that Phalanx and Phalanx II have such a low enhancing skill gain post 300 skill. By level 99 (if SE still plans to go that high) Rdm will have an enhancing skill reaching near 400, and with gear available that is already obtainable. Why is it that the new equation is so exaggerated post the 300 skill mark? Even if Phalanx went up to 40 mitigation it wouldn't break the game. Additionally, with PLD reaching the 300skill+ mark Phalanx II is starting to become less appealing since it gains very little potency beyond 300 Skill (between 300 and cap of 437 from gear/merits there is only 3 mitigation gain). Why is it that the formula had to change to be weaker even though there are NM that hit in excess of 500+? How is it in anyway game breaking to allow mitigation to go up to 40?
