Thanks for all the answers.
And no - I was not clear. What I mean is that if I leave the AoE effect blank, the spell will do 10 dmg to 1 target on touch and cost me 10 magicka. If I increase the AoE Effect sliver once it will pump it immediately to 10 ft (the minimum Area value available at the altar). But the magicka cost and required skill does not budge. So a 10 ft area spell costs the same as the same spell with no area effect.
The cost will start going up as I Increase the area of effect beyond 14ft only. So basically there seems to be no reason not to make every spell an AoE of 14ft as it will cost the same.

Just checked and it works as it should for me, i.e. 10 feet AoE costs more than none etc. Using FCOM and Supreme Magicka, so I'd guess it's LAME.
Something funny happened on the way to completing the Shadows in the Struggle for Power quest, I lost the Dread helmet. I've checked all my homes and I just don't know where it is. Any suggestions or am I screwed.
I'd guess either live with the consequences or add it via the console: player.additem XX06EA40 1 (change XX to the load order of OOO.esm).
