Created with raiding in mind. 

GCD attacks are on  left hand buttons to prevent interrupted casts and to encourage slide-casting.

Instant and OGCD attacks on right-hand buttons for movement when slide-casting isn't an option.

GCD heals/shields are on right-hand buttons for casting shields during movement IF required to prevent death, but out of the way on bar 3 (WXHB).

Mitigation has been kept to left side buttons on both bar 1 and extended bar to keep them grouped (Personal Preference). Longer cooldown spells and Kardia are kept on bar 2 Expanded.

The expanded bar is set to the same spells on both 
LT->RT/RT->LT.
