Ever heard Deers screeching? I don't like those voices too. Reminds me of Spriggan.

ice wraiths, sobs are hard to hit with a bow

The Thalmor and the Nords. Racists/nationalists are the worst. The Falmer are my enemy... but I respect them.

I had an opposite experience, I think I've only fought with them twice

I'd have to say any sort of Ice caster while you're playing on a character who isn't focused on magic mitigation or much defense. The one enemy that has caused me to shout obscenities while playing

Mudcrabs. I'm being completely honest. I'll be sneaking trying to get a sneak attack on an enemy with my bow and then BAM! a mudcrab either attacks me and or it looks at me thus no longer making me hidden. they are just annoying.

Wish I could say I hated any of them but I don't.

I tried to sneak attack M'aiq once. He is way too knowledgeable about everything if he is able to notice someone on a cliff using him for target practice.

My worst fear was frost trolls and second was sabre tooths but now i can kill them with a few hits...i now hate the Falmer

chaurus, those anoyying little [censored]

draugrs, dragons, and falmer. too common.

I HATE falmer. So annoying and can be a right pain at lower levels.

I once Fus-ed M'aiq off a waterfall. He didn't see that coming.

I'd say I hate Frost Trolls the most. In Oblivion is was because of their unrelenting hits that had a knac at staggering me. In Skyrim it's because of their unrelenting health regeneration.

Dragons, Especially at higher lvls. I frequently find myself trying to get to my objective only to feel a sharp gust of wind and me thinking "please, just circle around and leave me alone...."

And if it's flying too high to detect me it usually flies off.... and attacks a distant town... Full of quest related NPCs .

Forcing me to take a detour from my current nearby objective, run half a mile to the town, Kill the dragon, only to re-load the save because someone stupid enough to go after it with an Iron dagger got killed!
