I think they should remove power surge and reduce the CD on Jump to 30s.

Bonus points for (a) invuln frames in general, or (b) at least making the DRG "hit box" track to their original position only. Currently, you can be tagged by an AOE as you drop down to the ground before you hop back to the original position. So a DRG with poor timing / bad luck can get tagged by PBAOE attacks, line AOE attacks, OR wide area AOE attacks when they use Jump. Seems excessive.
