Logged in on sunday A.M. for a bit and found a GV fight at a port that was conceled in fog. I have to say this was very cool, it was interesting moving around fairly conceiled unable to spot enemy GVs till about 1 to 1.5 away. Made me think of what the cold foggy mornings in Russia might have been like.

Anyway it was very nice, it seemed even planes had a harder time spotting the GVs. If you have the opportunity to do this when the fog is around, you should, you might really enjoy the "cat and mouse" aspect of the GV fight. Screws with frame rate a little though.
This experience confirmed for me that GV icons should be removed. IMHO
