My english isn't my first language so I got hard time to explain.

I'm for she was trying to do. There is a lot of "discrimination" about Astrologian and misconception.

But Healer got strong relationship with his party. So I think we need to have a "systemic" view. You aren't only dps, you aren't only heal. And your co-healer(and other mate) is gonna determinate how you will play.
So I think it would be better if we took some real example like a1/a2/a3/a4 Thordan etc. And explain why Ast/whm/sch is better and how you play for ?
