Getting on the roofs by c4ing their tank and camping

People are camping on the roof by placing c4 on their tanks to make them fly then getting on the roof. Yes some you can destroy but some you can't and it ruins the game. PC players also have an advantage on console players and are so sweaty I want to enjoy the game but with console players too. Also the shot gun needs tweaked as people are using it as a sniper which isnt how shotguns work
