I totally agree with the OP.
Our guild has cleared NMM KP and EV and, without a doubt, given the choice we always take a ranged dps over melee for the reasons outlined in this thread.
One solution I heard was to scale ranged dps in terms of distance. I would tend to favor a slight dps advantage to melee due to all the running around and mechanics they must avoid. Of course, that may imbalance PVP, like I give a rip about that.
