How to kill a SCH

[Garlyle]

Lol ! Scholar have only one heal and no dispel in 30s

Yes, there's no Esuna. That's about it in terms of disadvantages of having one in 30s, because Eos. Eos means that even when the scholar's being assaulted, no cooldowns have to be blown in order to heal. When you assault Eos, the Scholar heals them.

Which is kinda how healers work. They have to actually be able to heal. The only way a WHM gets to do any healing in 30s is by blowing a cooldown, because you will be interrupted by one of the many attacks headed your way any time you try.

You're a Scholar in PvP, apparently. You should be fully aware of all of this.
