What's Scholar like?

[EaMett]

Once I get it to 70 I'll never heal with it again. Not in it's current state anyways.

SCH is, imo, the most gear dependent healer. Like you, I also found that it was the hardest healer to level.
I think there are plenty of reasons for it but a lot of leveling content is downsynched in odd ways, your tanks often aren't geared properly, you're often undergeared yourself, you don't have your full skill set (excog and fey union are a huge relief with tank healing), it's often hard to anticipate damage in that content, etc. etc.

It really shines at cap however with a bit of gear. And is probably the most reliable healer in 8 man. I only ran a couple of expert roulettes (usually prefer running those with whm) but it was a breeze.

SCH is however not for you if you like to keep people topped off. That's just a huge mana drain/waste of aetherflow stacks. It's also not a good match if you would rather react to damage intake rather than anticipate it.
