On my first character, I did the first Oblivion portal at level 1 and it was easy.
I created a new character and decided to just explore, and made it to level 35. Some NPC wouldn't offer training until I closed some Oblivion portals, so I decided to go do the first one. Instead of fighting the easy scamps, I had to fight multiple Daedra Spiders, Storm Atriochs, and Xiavige whatevers (look like blue people with wolf heads that can summon). Needless to say, the guards weren't very helpful and I had to kite things for several minutes while my conjurations slowly took them out. THEN I entered the portal, and was welcomed with even more of these enemies because the guy I went in to help aggrod like ten of them while running up to me. It's really hard now. :/
EDIT: My first character was melee only, my level 35 character is a pure mage (mage class, "The Mage" sign, with 100 skill in mysticisim, alteration, illusion, restoration, and conjuration.. destruction is going up kind of slow for me and it's hurting).
