The expert spells for destruction is the spells that deal most damage on one target, correct?
So the apprentice spells such as 'rune' won't actually be that strong at end game?
I just ask because I can see that the 'rune' spells is unique as none of the spells at expert \ master level have this type of function.
Would be a shame if it wasn't ment to be used for end game.

(Oh and by the way, can any race become a good Mage?)

That is one thing I don't like about magic, yes the runes are underpowered at endgame. And yes any race can make a good Mage but high elf and Breton are the easiest
