So one of the things I really DO NOT like about WHM is how the job basically collapses down to chaincasts of Glare with the occasional Dia thrown in to not make it as monotonous.
Something I think would help the WHM immensely is if we took the Stone skills and turned them into a skill chain like:
Stone 1 => Stone 2 => Glare
Stone 3 => Stone 4 => Glare
And later upgraded Stone 1 with Stone 3, and Stone 2 with Stone 4. Also, all of these spells should have a 1.5s cast time to allow for better skill weaving.
So what makes our skill chains unique is that instead of just increasing DPS potency for keeping the chain, they should also do the following:
Stone 2/4: AoE HoT (Gift of Earth?)
Glare: AoE Heal
So we're not stepping on Medica, Medica II, or Afflatus Rapture's toes, the AoE heal and AoE HoT shouldn't be all that big, but should still be there nonetheless. If this was copied and pasted onto another class, SE could change the AoE HoT or AoE Heal to a shield.
Even though this will likely cause a ton of overheal, the changes to the tanks with aggro have shown that healers can basically do whatever they want and if the tank is half away (let alone halfway competent) the healer will never pull aggro - which means we're safe to just let the DPS skills overheal as that will provide the WHM with some baseline healing that can be used along with built off of if things go sideways.
