Best Battles you have been in, or watched in your game, cause of Dawnguard... I have two..

One: The 4-Way Fight of Arcwind Point!

Team A: Me, Derkeethus, and Durv. (Bad speller so shortened the dragon's name).
Team B: Legendary Dragon x2. (Yes! TWO of them!).
Team C: Draugr Death Overlord x2, Draugr Deathlord x4, and Skeleton x10+.
Team D: Frost Troll x2. (This Team got destroyed quickly).

Also.. Went to Soul Cairn to have some fun... And watched a Durv. VS Durv. fight. (Yes, you can get the dragon to fight himself.)

What are ye's?

I sort of missed out, my level 57 using expert destruction can chop through anything with Marcurio. Those two Dragon on the lake were tough though. And I have a 55% Elements resistance. 300 health and one bite took away about 1/3. If I had used VL and didn't have Serana I would have taken them down easily.
