What RDM could use is support as other's have stated. They should be able to compete with BRD's and MCH's.

1.) Composure: Increases own physical damage dealt by 10% and magical damage dealt by nearby party members by 10% Both effects are reduced by 10% every 4s. Cannot be used while Embolden is up. (Recast: 80s)

2.) Embolden: Increases own magical damage dealt by 10% and physical damage dealt by nearby party members by 10% Both effects are reduced by 10% every 4s. Cannot be used while Composure is up. (Recast Lowered to: 80s)

3.) Manafication: Doubles current Black Mana and White Mana levels. Additional Effect: Restores 10% of maximum MP.

4.) Enchanted Riposte: Damage Potency Increased to 250. (210 Original)

5.) Enchanted Zwerchhau: Combo Potency Increased to 320. (290 Original)

6.) Enchanted Redoublement: Combo Potency Increased to 500. (470 Original)

Now it has a similar level of support to the Bard, and their melee combo got a upgrade of 100 potency putting them more in par with them. And they also got the same mana utility as SMN, sure they have a 2min recast but their spells cost less mana than a SMN.
