I agree, bring it all.
Everyone says the MA is for arcadey style play, but to me that's the dueling arena. There are so many different things that happen in the MA with missions, base taking, GV battles, there will always be a lot of action whether it's night, high noon, foggy, rainy, whatever. I'd love to dogfight through a fog bank twisting and turning just catching glimpses of my enemy. Brings a whole new dynamic to the game.
I would say give it a shot for a tour and see what happens. There's always going to be different opinions on the forums, and this is such a small percentage of AH players.
The real measure of if something is working is how many are in the MA at a given time. I wonder if HTC tracks that with a log?
Bring us weather and a 24 hour clock!:aok
