I hope there's a 4th healer in the future and that healer be a Meele. But if balance is the reason to the 4th Healer wasn't made yet i believe that a 4th Healer is out of question, unless they release a 4th healer even unbalanced, i already lost my hopes in Healers Balance after +6 years playing this game. I'm just waiting for new Jobs Updates to see WHM being nerfed directly ( nerfing their own skills ) or indirectly ( buffing af SCH/AST skills ) always being.

Anyway, SCH at SB was "almost a meele", you had to stand in Meele position to spam Miasma II always that debuff goes off ( 10 secs ) to improve your damage, a Meele Healer could be something like that where their DAMAGE skills was based on Meele style, NOT their HEALING skills, Healing Skills should be ranged like any other.

PLD and GNB are similar, as WAR and DRK are similar now as well. So AST should be focused in only one Stance, Nocturnal or Diurnal ( Nocturnal is useless to me, i just play NOC if there's another AST in my group already in DIU, so i wouldn't miss NOC at all especially now that DIU got Shields to cast ), that way we had 2 healers based on Regen Kit and 2 Healers based on Shield Kit, so the new Healer could be more Buff based too, so there's another 2 Healers for Buffs ( AST and their cards + the new one ) and 2 Healers for Raw Skills ( WHM with their Strong Healing and Damage + SCH with their strong Damage Mitigation and Shields ).
