Oh? I thought spellcrafting was removed? omg omg my excitement level is going through the roof. it's still being added in? I really really want to make healing rain spell by combining restoration and rain.
Swen specifically mentioned that spell crafting (as well as Spirit Talking) isn't in the current EA build, so it's not cut or anything. Had the same worry myself, though.
To stay on topic: more than anything, I hope you'll be able to find a use for currently worthless spells with spell crafting. Making an offensive version of Steam Lance by throwing some blood into it would be sweet.
