Vulcan is completely overpowered and pay to win. If you have the incendiary rounds and heat immunity augment you can continue to shoot forever, burning other tanks without overheating, and incendiary rounds is already so overpowered that you only need to shoot a player for one or two seconds to kill them.

Yeah, the last time coinboxes were in the game I spent $1 and got 1000 tankoins from the coinboxes,kept buying them till I ran out. I got 300000 crystals for $1.
