In my opinion, all destruction needs are some master level spells that ditch the nonsense "Higher the level, bigger the spell, longer the charge," and are instead the most practical and effective spells there are for combat. If it was that way, then the Mages could literally be able to fight without any use of other combat styles.
As I said above (perhaps angrily so), I don't think Destruction needs to be "fixed." However, I really like this idea. Regularly casting master-level spells for combat would be nice, as well as some expert-level AOE spells (I'm annoyed that they're mostly stronger, more expensive apprentice spells). I'd like walls, runes and cloaks to benefit from dual casting and from the Augmented [Element] perks as well; currently those things have no effect on those spells.
