Well, for sure the thing that gimps it a bit is the fact that there is no way this class would work with force spells - as it is not an element per itself.
Also, the Inensified Spells ability is intended to work only with spells that deal damage capped by a die number. For instance, this ability will not work with Scorching ray. If the wording is unclear, I'll gladly accept propositions as how to change it.
