Okay so i have heard rumors that dragons do in fact disappear at the end of the main story-line. Can anyone tell me if this is true because i'm not gonna do the last mission if that's true. I play this game so i can hunt dragons i don't want to lose that.

I still find them often...

Never fear, they don't disappear.

Nope, they Come more often. Some say about 200% more often?

Unfortunately they do not stop spawning.

Unless it's a post-1.5 thing (which I doubt) they don't stop.

My dragon encounters have got less frequent after finishing the main quest. I did finish the main quest after the 1.5 patch. They did not stop, the frequency just became smaller.
