I'm a destruction/conjuration/illusion mage.

Really love using lightning spells, because I think it's awesome to zap someone dead and send them flying.

However, if you choose the last perk disintegrate, which is really good, there are a couple of problems.

First of all, you can't raise their corpse because they turn into a pile of ash. This is understandable considering they are in fact a pile of ash and not a corpse, and doesn't bother me that much as I primarily conjure daedra in stead of raising corpses.

But a much bigger problem is that if you kill a dragon with this perk, you do not absorb their soul. This means you can't unlock new shouts. I was forced to respec to fire in because of this, and while burning things is cool, it's not as cool as zapping people

Actually you do abosrb the soul, try it out.

I agree with the awesomeness of zapping stuff. THere's general unreliability with absorbing souls tho, so you might want to test it more extensively to make sure the perk is the problem.
