Well, let me say this because this was the most [censored] I have ever experienced in my life on Skyrim. I'm a Bosmer. I'm minding my own business trotting along from Windhelm to Riften. In the distance, a dragon is flying over a tower. This dragon (f*cking as*hole) swoops over and starts fighting a giant.
1st time. Dragon and Giant are fighting. I stupidly go in for a closer look thinking "oh cool." Dragon and Giant both see me. STOP fighting each other and tag team me as*. I felt like I was in prison.
2nd time. Dragon and Giant fighting. I hang back. Dragon kill Giant. Dragon THEN kills me because he landed on my head, breathed fire on me and then chomped me to death. I was pinned against a rock.

3rd time. Giant and I tag team dragon. Dragon dies. GIant is furious I took his kill. Clubs me to death.

4th time. Giant and I tag team dragon. I let the dragon kill more of the giants health. I've almost got the dragon completely killed when THE MAMMOTH OF DOOM SHOVES HIS TUSKS UP MY AS*. I died again.
5th time. I kill dragon. I run like hell after I absorb soul and loot. No a [censored] was given.
