Is it going to be new 2hour's or is it going to be the ability to add upgrades to the current 2 hour abilities?

I'm thinking up graded version would be the ideal thing to do. Increase time duration, conserve mp bonus, MAB bonus, magical accuracy or crit hit bonus while under the effect. There could be a lot of ways to go with this.

I wouldn't hold my breath for any aura stuff tho. RDM's role atm is to increase duration of buffs. not to walk around a glowing buff factory. If anything I'd rather see more duration thrown in and more increases to there strengths such as stronger phalanx and stone skin or maybe even an increase to the amount of blink shadows.
