I'm a fan of making pure destruction mages focusing on the elements. It kind of svcks that it's not very strong late game, it should be powerful and I wish armor made the spells weaker like 25% weaker with lightarmor and 50% with heavy (or maybe less). I still use robes and mage armor because I prefer to role-play even if it makes me completely weak. And also I wish there were more elemements that would be awesome to me personally. I love magic especially the elemenal powers. I wish I had Earth, Wind, Water (Or at least mixed with Ice

). It would be awesome if the elements had to be combined to make other elements. Say If I had Water in one hand and Wind in the other and when I dual-casted them together it made an Ice spell.
If magic was like what I said above i'd be in my happy zone. I can always wish though and hope for TES VI with an awesome magic style. I love heaps of spells as long as they aren't stronger variations with the same moves. Like if I could put my hand to the ground or shoot some sort of spell/ball at the ground at it created a giant fissure/crack or earthquake that would be awesome. Or if I could use wind to blow things away and maybe even float

I don't want it to be overpowered and more like an MMO or something if that's the case. But personally I think this would be a dream. Fusing elements to create new ones.
Maybe use similar combinations like in Naruto? Though I wouldn't use Yin/Yan and all these extra elements may be too overwhelming
http://naruto.wikia.com/wiki/User:Omnibender/Elemental_recomposition_table <-- see the Two Element combinations (it's the first graph).
I think the one above is slightly too complicated and is getting away. I'd stick to Fire, Wind, Lightning, Earth, and Water.
And then have some combinations. Only like maybe 1 combination for each element. So Wind + Water = Ice, Earth + Water = Wood? (Maybe Earth + Fire for lava or Earth + Wind for sand)
Well I think I'm going way off topic or at least too much advance on Magic in Elder Scrolls haha. I just love the idea of 5 basic elements and fusing them to make a new element.
Sorry for so much typing that no one will probably read.
