The only thing I really find disappointing about RDM is that the melee combo is just a short burst phase with no real decision points at all. When I heard about RDM originally I imagined a class that spent far more time in melee that it currently does; what they have is fine, but isn't really what I was looking forward to when it was announced.

I don't need the insanity that was old NIN or DRG and I probably wouldn't play it if it was that complex, but melee as it is right now feels lacking - even for a burst phase. If they want to keep it as short as it is or not add reasons to be in melee when mana is lower, even something as simple as interactions with whichever mana was higher going into it would be a welcome addition.
