I would never call GVs cockroaches. This game is one of the best (I would say THE best) tank games online, and CUSTOMERS that support the game drive those GVs.
Not sure how quick a change like that would take, but I also don't think it would be worth it. It would be divisive of the community in the game, because we already get people screaming for users to stop resupplying, stop GVing, and come help them do what they are doing. You don't have to ask for a participation trophy to play AH, so play it your way and let the public shaming stop.
