I had to stop playing this game the other day because the frequency & absurdly bad timing of dragons was driving me insane. I was doing the Dark Brotherhood questline & after I walked out of the Abandoned shack -- dragon; when I fast traveled to Falkreath to go to the DB Sanctuary -- dragon; when I did EACH of the 1st three contracts you get -- dragon, dragon... dragon.
Today I got Hearthfire (which is great, btw) and in the 2 or so hours I've been playing I've had to fight 5 *** dragons. I mean seriously, there comes I time when I just want to play & not stop what I'm doing every 5 minutes to fight a damned dragon. There's nothing wrong w/ dragons per se, but like I said, their frequency & bad timing needs to be patched -- at least give us a setting option for dragon frequency: rare, common, frequent & daily... or something to that affect.
Rant over, troll on...
