1. AI is generally poor. Dragon Priests in particular have a problem with their AI. If you dodge their spells for long enough eventually they will stop casting entirely and just stand there letting you attack them. Even on the named ones with huge amounts of health. AI also seems to have problems dealing with backpedaling yet again and also if the player is standing on elevated terrain.
2. The low end Destruction spell Flames deals considerably more damage if you stagger cast it rather than holding it down. It also uses less Magicka. Cast for 0.5 sec, stop, cast for 0.5 sec, stop and so on. I think this is because the damage over time after stopping actually deals more damage per second than when they are being hit by the actual spell.
3. Some texture resolution sizes in the game are REALLY low and I mean to the point where you can see pixelation. Most of the time there are poor textures on the players clothing from the first person view.
4. The UI doesn't respond very well to the mouse at all. Noticable as soon as you hit character creation. Clicks dont register at all or the game thinks you are clicking somewhere else. It's really sad to have to navigate a PC UI with keys.
Im enjoying the game a lot so far but these are my main issues with it.
