I love how people imply that you can overcome the internal mechanics of SCH, but you can't do it as AST. People are assuming that it's a broken job just because they can't play it, it's pathetic. I love the inherent complexity that AST has and how you have to be smart about using everything.
Also, another thing: don't forget that Fey Illumination is also an AoE, so if use it near an AST/WHM, their AoE regen will also be boosted. It's also a gap filling skill, which is fine. It's a very nice skill to have and boosting both healers is what makes Eos so valuable. SCH is not supposed to be a bad healer, but people deny it's inherent complexity and how it is harder to master than WHM. And they also deny that AST has some tools they only have with cooldowns or with stacks, as if it was not a thing you need to work out.
