I finished the main quest line and I realised I've never seen anything "stagger" or even halt in the slightest from my dual-cast flames. Or is flames like the only destruction spell the Impact perk doesn't affect? Or is it, gasp, bugged? Any thoughts on this?

And on the subject of destruction being weak - it may very well loose power compared to melee after lvl 30 but... I suspect people are using fireballs too much. They svck. You have to use Flames, and in very short bursts with 1 second between each. You get the exact same DPS as if you keep firing because of the burn effect, only your mana never runs out. I'm only playing on adept mind you but I never had to use any potions during the two boss fights, the mana was mostly spent on dual-cast Heal (not fast heal, that also svcks for mana efficiency). Also, keep them legs movin'

Anyway thanks in advance for any replies to my Impact question above!
