Not everyone has a newest iPad or Galaxy. There's a lot of people (like myself) that have older devices. I have an iPad 2 and sometimes the game lags so bad I can't even play it. And other players have the same problem too. Like i said before,the maps aren't that big and they have a lot of objects. And with a melee weapon you can get to point A to point B pretty quickly (especially with the berserk boots on). I can't see cars on sky islands,two castles,atlantis,paradise resort,arabian dust/desert whatevr its called,ant's life,inside the code (that would be funny to watch),space station,or that FNAF map. Adding boats to the paradise resort map would be useless because after a certain distance you can die and there's trees everywhere so it would hard to shoot people from a distance and a boat. Helicopters why? There's already jetpacks and those are bad enough. Tank? The mech is basically a walking tank. Has armor and shoots. I don't think they're a good thing to add (vehicles).
