hehe cliffracers make people jump higher then ghosts or dragons lol
Try swinging at a floating critter for five minutes getting nowhere when there's no water in sight for you to get away from him and get out of combat? Oh, and arrows aren't very effective either, and the magic system is...difficult, particularly on a keyboard.
I grew to hate Cliff Racers pretty quickly when I played Morrowind. They were a useless enemy to fight, and an endless annoyance. Not to mention they can spot you from miles away and chase you until they either die or you find water to dive into.
With flying dragons, you can ignore them if they're not immediately hostile.
