I think the issue in this game is that melee is too strong, not that magic is too weak.
That being said though, I like the master level spells. In case you didn't know, Fire Storm does more damage to enemies closest to you and less to those far away. With Fire Storm just yesterday I cleared out a mob of high-level bandits (marauders I think) in one Fire Storm spell. I also play on adept (aka "normal" difficulty) so that might factor into it. But I also have both Augmented Flames perks and the Master perk to reduce cost to 1/2.
But I also use other spells besides destruction. For example, I'll use a Mass Paralysis before using Fire Storm, so I can cast it without problems.
Nice Marmot, definitely hear you, especially on Ice Storm. Dual-casted Ice Storm with all the perks will take dow ANYTHING, even frost resistant foes. I've 1-shotted draugrs and nords with dual-casted Ice Storm.
As I read it on UESP, Firestorm does 100 damage at point-blank. Dual-cast Fireball does 88 (Dual cast multiplier is 2.2x damage and 2.8x mana). So.... for being able to move while charging up, using *FAR* less mana, and having a longer range by nature of Fireball being a projectile, I lose... 12 points of base damage.
For the amount of mana that Firestorm costs, I could dual cast Fireball nearly six times.
My source: http://www.uesp.net/wiki/Skyrim:Destruction_Spells
Fireball does 40 base damage at a cost of 86 base mana.
Dual-casting ramps up the damage to 88 (2.2x) at a cost of 240.8 mana (2.8x).
Firestorm on the other hand does a max of 100 damage with a base cost of 1426 mana.
Do you see the problem now?
The master spells would be worth something if they actually were efficient... but they aren't at *ALL*. :shakehead:
