I would like to point that the melee part of the RDM gameplay is not very developped.
You technically spend 90% of your time shooting spells, possibly at range. You only charge to unload 3 gcd once a minute.

Don't get me wrong, it is a fun job. But don't expect to do an actual melee caster hybrid, because you won't. You are a caster with a bit of melee fantasy.
