I never got too far into skyrim to really know that, i have a extremely bad habit of getting to a certain point into the game, realise i'm not even halfway done even in the main quest and i'm alredy way too high level (by simply playing normally mind you), and i somehow lose interest in that run and start over.
The one thing i never got to see was alot of dragons. Outside of the ones that are always near words of power, the random dragon encounters everyone claim to be way too common almost never happen for me. So i'm gonna ask, are the random encounters supposed to happen more often later in the main quest, or am i just unlucky in general?
