honestly, if youre looking to save space, id make a hybrid overpower/battle stance macro. leave execute on its own, since its useable in more than one stance, and sometimes results in a worse gain than an overpower does (i.e. you generally only want to use execute if sudden death is procced and theres 5s or more left on your overpower proc. using execute on a mob in execute range is pretty much a no-no since your normal rotation will generally be better. you only want to use execute in execute range when all other options are exhausted and you can ensure youll have enough rage to keep the rotation going in another second or two).
