Its plausible they are holding over until a future expansion pack but that could just be wishful thinking on my part.
Also this spell system is not really different from past game there is just some new spell types an pretty animations and that has blinded people because of the fluff. The only two noteworthy changes is the dual casting and the charge and cast spells and all of that could fit into a new spell creation system.
I would love to see it in the next expansion pack.
No, I know it's different because in the CK it looks different.
Even the enchanting effects are different
I'd want to combine Magelight with one of the Rune spells. The rune is placed wherever the light hits, and after establishing itself the light acts as an attractant for whatever enemies are nearby, causing them to come by and activate the rune.
... and here lies the naivety when it comes understanding the system.
How would you know that combining those two spells would do that? More logical would be that this combination creates a rune that casts magelight on whoever steps on it.
