Ok, but what about Infuriate? And it's interaction with Fell Cleave reducing it's CD? In fact, what is the comparison point for Fell Cleave outside of IR? What about Inner Chaos? What about Onslaught? We could compare Mythril Tempest to Holy, but what is the comparison for Decimate, the AOE gauge spender? If we were to have WHM (or any healer) having parity with WAR, it'd need like 3-4 more damage buttons. Personally, though, I don't even necessarily want full parity with WAR, I just want to take the most impactful parts and use those, to maximise engaging gameplay additions while minimizing button count additions. To that end, I'd take the idea of a 0-100 gauge, make it build via any non Lily spell, and spend it on an AOE heal that is GCD, but damage neutral, because we are a healer. Then I'd add 1 (one) 15s CD GCD (call it Banish) that is slightly stronger than Glare but builds gauge faster than Glare does, and reduce Dia down to 12s duration. We'd Dia every 5 GCDs, Banish every 6 GCDs, and Glare when we can't do either, which would look
something like this (sorry for the error sounds). I think it's still 'less stuff to manage' than WAR, in terms of 'what we do for our damage GCDs'.
Also, to save on button space, Cure 1 and Medica 1 can upgrade to Cure 2 and Medica 2 at 30 and 50 respectively
