DRG the easiest...yeah...no.

Easiest job is RDM. All you have to do is cast Jolt into Verthunder/Veraero or Verstone/Verfire into Verthunder/Veraero if you have a proc. Then do your 3 melee combos and verholy or verflare. No positionals, no timers, no dots, no nothing. But hey, the job is so hard to manage they decided to make half of your casts instant.
