i have cure set to r2+x for both hotbars. i use regen quite frequently, where a cure isnt appropriate, or just where i need a little extra heals . i have it set to l2+triangle. but, one setup wont fit every player. if i could, i would take some pictures of my hotbars and post them, but im at work. i only use 1.5 of my hotbars, but i have every skill, and some cross class. i dont use aero 2, because it has a cast time, and it doesnt seem to be very worth it, unless im on my own. if im on my own, i start with cleric+aero 2, followed by aero as soon as the GCD is down
