I have points in destruction (most), conjuration and a couple in restoration. Everything is easy unless I get overwhelmed. 1v1 I can smash anything as dual casting allows for pretty much perma stun with its stagger effect, the main weakness is running out of mana, which doesn't happen much with 250% mana regen and around 400 mana.
Hardest guy I've fought by far was Morokei, this bastard will nuke you in two spells and as he uses lightning they're very hard to dodge! He also never runs out of mana. The loot is definitely worth it though, if you're a mage.
I will also add I fought Morokei with no dragon powers, I did a lot of side quests before doing the main. I was literally about 10 hours into the game about level 15 before I killed my first dragon.
