The games bread and butter was the dragons. That being said, I don't understand why they didn't take time to make dragons better and unique. When I first start finding named dragons I thought they would be challenging and use crazy shouts against me. But no, they are scripted to act like a normal dragon and the only thing that makes them unique is their name. Even the endgame boss acts like a normal encounter with the exception of the meteor shout he does.

It also bothers me that the shouts the dragon born has are effective against casual enemies but they're pointless against dragons. Dragonrend and Clear Skies are the only shouts that can help in a dragon fight. Sure there are others like Frost breath or mark for death but they have little effect and the time it takes to reload isn't even worth it.

Bears, oh my got I hate them. Dragons, they're just too common and they keep killing NPCs. And any spellcaster. The way they back away from while they're zapping me... God it drives me batty.

The bears and spellcasters annoy me in a good way, like it's annoying but it's cool anyway. Dragons are just annoying and stupid because they're so week and so common.

Greater Bonewalkers.

Oh wait wrong game...

I'd say anything that shoots ice storm at me is probably the most annoying.

No no no. Youre doing it all wrong. you have to block their tail whips, not their charges. Blocking proves futile when they charge, due to the high amount of frost damage they do when they charge. What you gotta do is right after they charge run up close to them so they get into defensive attacks, hence the tailwhip. Theyre easier to block and dont inflict as much damage.
