Just an idea of my macros so far, still young though

DPS (Main)
/stopmacro [channeling]
/castsequence mind flay, mindflay
/cast mind blast
/cast gift of the naaru

DPS (Proc)
/stopmacro [channeling]
/castsequence mind flay, mindflay

Round Robin Renew (Great to keep my main alive versus focus fire)
i)
/tar {FTL}
/cast Renew
ii)
/cast [@player] Renew

Round Robin
/cast Psychic Scream

/cast [@player] Power Word: Shield

And then I just have renew and flash heal on the tool bar for 5 x cast on target.
