I think you guys are playing with fire.  There appears to be no development going on, and you want to double the price?   
My guess is AH would lose 25-50% of its remaining subscribers.   I think a price increase would hasten AH's demise.
Hmm, I guess I didn't think that through - if double the price, you will most likely lose some subscribers.  But, if you lose less than 50% of your existing player base, you come out ahead, right?   
I still don't think its a good idea, though.   The cost of online gaming has been coming down, and moving away from subscription-based.  
Nope.  Still think a free base plane/vehicle set is a better option.    Appreciate the discussion though.
