Seriously. I got far enough into the main quest so random Dragons would appear and each one that does simply circles above, roars a little bit and then flys away. I jump up and down shooting fire balls and arrows like im trying to wave a plane in, but to no avail.

A bug perhaps... Or are Dragons just misunderstood? Anyone else having this? Because I really need the souls.

Yup, i see a random dragon three times in a playtrough (of around 60 hours) if i'm lucky. And atleast two of those fly away without fighting Stupid, lazy, good for nothing overglorified flying lizards...

That is weird because I am always attacked by dragons its like I cant get them to stop, do you guys have dragonrend because that might be useful to put them on the ground and then start attacking then they would be bound to you!

There's a few different encounters with dragons. Some circle then fly away (indicating that they exist, and sometimes it's one that lives at a word wall... that's scripted though, and not a random event), some circle THEN attack, and still others swoop in, silent like an owl and land RIGHT in front of you and attack.

There's probably a few more I'm forgetting, but no... not all dragons are out hunting Dovahkiin. Besides, it's duck season.
