I honestly don't think it needs more than maybe a single oGCD dps skill to use when Fleche and Contre are on cooldown, the removal of Embolden's drop-off, and the addition of non-damaging party support in the same way BLMs oGCDs are self-serving.

5.0 feels like a real chance to move away from stringent DPS-check-based encounter design to open party comps that might allow different, equally effective ways to get stuff done, and it wouldn't make the game any easier, just more accessible even at a meta level of play for the tiny fraction of the community for which that matters. Doing something like the above for RDM feels like an interesting way to open the floor for more varied and approachable encounters at all levels of play.
