This is a HUUUUUGE spoiler! Why in the world wouldnt you put a tag on this? ... Wow, how could you do this? >_>
Calm down. Breathe. We'll get through this!

The only possible "spoiler" is that he talks about dragons, which has been talked about everywhere by everyone since the game was announced. Skyrim has dragons. No real surprise there.
And actually, if we're going to get this technical, almost every single mod on the forums would have to have "spoiler" in the title because it's modding something in the game and has to describe what it's modding... and thus, it's telling us about stuff in the game!

Alright. I finished the main quest and have moved on to the faction quests, but it it really annoying, and time consuming, to get anything done with dragons constantly pestering you. It seems they attack me 2-3 times whenever I walk a short distance outside. They aren't even difficult anymore, just annoyances. Does it even make sense for them to be aggressive? Shouldn't they be peaceful now? Anyway, I have enough dragon souls for every shout in the game already. It wouldn't be as bad if souls had other uses (Like lowering shout cooldowns. That makes sense, all souls are is knowledge, right?) but I'm not sure they do (if they do I haven't come across it yet). I want dragons gone. NOW!
I haven't encountered anything that would make me believe they should no longer be aggressive, but maybe I'm not where you're at yet. Dunno. I do agree (and knew this was gonna happen) that dragons are far too common, and are drastically inferior to what we would expect dragons to be from most other lore. There are likely to be several mods before long addressing both their physical attributes and their frequency of appearance.
