I've loved RDM throughout the whole franchise and I was so excited when they announced it for SB. I was not disappointed.
The concept is simple, easy to understand and if you're paying attention, easy to execute. (Yes I have got lost in my rotation and Dualcast Jolt... Shush...)

For those people moaning that it's "too simple", I am reminded of a quote I used from another RDM player in FF11 (yes they are different, I know )

Ringthree quote:
These people live on the edge between sanity and insanity, reason and psychotic episodes. If you ever interrupt the "refresh, dispel, refresh, gravity, refresh, OH CRAP CURE, debuff, nuke, refresh, OH CRAP CURE, dispel refresh" cycle, you my find that the Red Mage's armor will be red because it is stained with your blood
I'll take the fluid motion and weaving of mele and magic in 14 over the stress of 11 any day!
