You're not going to avoid having to change bars without hurting yourself in the long run on PS3. You already have the only macro's I'd use to save space really. Personally I have an issue with aiming Flaming Arrow on PS3 mostly because I can't position it intime during my oGCD and not sit on my GCD for a second or more so I just macro it into my abilities. The circle will appear when it's ready and will just sit there until you press X, kinda handy!
