I thought the graphical updates would apply only to indoor lighting but it seems to apply to everything, and it looks great. Fire effects on my weapons, the glow around rune nodes, etc., it all looks much better. And I was already pretty happy with the graphics, so this is great.

I will say it is throwing off my visual cues in combat a bit. I don't use addons, so I figure out what's going on by graphical cues that I've gotten very used to seeing. With the new effects, I have to re-adjust. Kind of a weird side effect that you don't get in MMOs that aren't focused on graphical cues (all other MMOs). I guess it would be nice to have notes about these changes, but I'll adjust naturally. Overall, very well done, though.
