I would just give rpr's arcane circle a 5% buff instead of 3%. and SoD being oGCD would be nice.

The compromise of a 5% buff jobs are lower damage and with rpr having around average damage and average 3% buff, puts it in an awkward place.

Regarding the "rpr is easy" comments. Every job is easy if you're just full uptime doing standard against a dummy.
The difficulty is in the management of downtime and not building guage to line your buffs up with the raid putting you into non-standard.
