I'm not sure what excatly you mean with "easy on the hands", but if its about having to hit less buttons, I'd say MCN and possibly BRD are a less good fit. Specially MCN is being joked about to give people carpal tunnel syndrom... DCN has some "burst-phases" where there are a lot of buttons to hit in close succession but it always felt a bit more relaxed than MCN and BRD to me.

RDM might actually be the best fit for you - its easy to play, not very straining on ones hands, I'd say, its not designed as support role and thanks to the dualcast you're still quite mobile.
