The Role Skill choices we have currently are stuck between being mandatory and useless at the moment. Personally I would love to see skills like:

Forced Induction
Ability - 3 min Recast
20 Sec Duration
Create a temporary bond with target allowing them to be affected by your spells as if they were in your party.

(In Raids this would allow a Healer to assist an allied Tank in an emergency with their full arsenal of skills.)

Absolute Mastery
Ability - 10 Min Recast
Duration 20 Secs
Your next Ability Cast will have no Recast Time. Can only be used once while engaged in Combat.

Dragoon's Blessing
Ability - 6 Min Recast
Duration 30 Sec
Automatically revive target to a weakened state upon ko.

These are all just fun ideas. Anyone others would be cool to see.
