SCH is trash in its current state
Sorry for the negative title but I don't think I'm exaggerating. What's horrible about scholar:
1. Can't use aetherflow unless engaged in battle.
2. Your rotation is so dull and boring it hurts. At 70 is Bio > Broil for 30 seconds and maybe Art of War if doing a dungeon and dealing with multiple enemies. You only get to have what seems to be a 2nd DoT at 72 in the form of Biolysis and then Broil 3. That still leaves you with a boring, dull rotation.
3. Mana is awful on SCH now, you will run out of mana very often, and there is no more BRD mana regen or Caster mana transfer.
4. If in dungeons, all you do now most of the time is wait for enemies to hit the tank and heal him/her, even though there is plenty of downtime to dps and kill mobs, but if you do it, you will probably run out of mana. The system punishes you for trying to dps with SCH -- I am not sure that WHM has these issues with mana as SCH does btw.
5. Why did Yoshi P and his team decide to get rid of Shadowflare, Bane, and Miasma/Miasma 2? From what I have experienced running dungeons, there is still PLENTY of downtime with bosses to do dmg on the side, even with the bosses using more aoes/etc, demanding more healing. This makes the flow of the fights awkward because you know that you could dps but if you do, your mana will suffer, or you are aware that you don't have the tools you used to have to deal dmg properly.
Please consider restoring some parts of the SCH kit. The most nuanced, fun, flexible healer is a sad shell of his former self in its current condition. It deserves better and the people who played the job certainly didn't ask for it to be this way.
