The SCH is fine in terms of healing. Due to my own stupidity and hardcore grind I kind of forgot to do my classquest from 30 to 45. Dont ask why, but yes I did. Even though I missed some rather very helpful healingspell. I still did fine in the dungeons up to lvl 45, when I realized my mistake and got the missing spells. So dont say they are useless, cause they are not since I did fine with very little tools at hand.
