Proficient on both classes.

Going from SCH to WHM, you will notice the difference in the tank takes dmg. On SCH damage would stagger all the time due to aldo, on WHM it just keeps on going, but you can heal bigger so dont fret too much.

No aggro worries on SCH, WHM - No Hots when adds are coming, or until tank has the target.

Knowing a fight routine really does help, for instance Garuda Ex start medica 2 when garuda cleaves, this will allow you to deal with the damage of friction without topping up anyone afterwards, however only do this for the 1st cleave, as medica will not wear off before the sisters come and most people will not cancel it (god knows why) so you pull aggro and most likely wipe the party. However, make full use of DS Regens, like you would fey embraces.

Cure bombing is good for dealing with melees who dont know when a cleave is coming, where as on the scholar you may need to lustrate them all or rouse fey, on WHM you can just Cure 3 the who is closest to them all and jobs done.

I would suggest running thornmarch a few times, it is a good healing exercise especially when you have bad tanks.
