Why is the healer class basically a one spell dps class?

What? This works brilliant on rdm.

Isn't that because RDM does not really have a rotation, but priority rules it follows? So it can stop to do a healer duty and not lose as much as something like BLM would lose if they were interrupted for let's say 5 seconds or more.
But I cannot really speak for both BLM or RDM, I have not played both to max level.
I guess Summoner too could find a moment between Bahamut and Phoenix to do healing duty, but it would be kinda awkward to pop either and then realize that I need to go heal someone because they got hit by raid boss. If I am an actual healer, Glare is a Glare is a Glare. Since they are all equal in contribution, I do not need to worry about missing out on an extra glare.

hmm i dunno, planning rdm melee combo around healing isn't that much different to planning it around mechanics

You don't plan anyways.

If you're using savior, you're using lost cure 4 because it's an OGCD and is basically a full party heal per use.
