Pure DPS class that easy to play to 80/end game (also on the hands)

[Enla]

I'm not sure what excatly you mean with "easy on the hands", but if its about having to hit less buttons,

They might have pain related issues with their hands like arthritis or carpal tunnel. Some jobs in this game can be rather painful to play for extended periods of time if you have a condition that affects your joints. I can't play MCH for very long for example without my hands locking up in pain, even with stabilizing tape to limit my wrist movements.

To the OP, I have arthritis myself and out of all the ranged classes the following are in order the ones that hurt my hands the least.

RDM > DNC > BLM >>> BRD > SMN (I haven't touched SMN this expansion however, but past experiences were not pleasant on my hands) >>>>>>>>>>>>>>>>>>>>>>> MCH

I'd check out RDM if you haven't already. It does have utility but it's easy on the hands and has pretty respectable damage.
