It may be a little dated but some of these things have already been added to the game in the last update (new kill-cams, underwater visuals).
What do you bros think? I'm hoping more of it gets added in updates, like the spears, lycanthropy skill-tree, dragon mounts, etc.



EDIT: Fixed link.

I'm sorry for not taking that into consideration.
