Ah, sorry, but it's quite disappointing. The gun is super imprecise and takes an eternity to aim, and then an eternity to reload. 15 second reload at tier3 is HUGE. It can damage and seriously hurt anything it faces, though, if you manage to hit.
Oh, I already elited and sold the tank, but yes. Oh god the fucking reload timer.
I had a game were the first random shot set me on fire, and I had no fire extinguisher. Due to all the burned out components, I had a 32 second reload time
I pretty much asked for the enemy team to come towards me and take me out of my misery because everything on my tank was damaged, or injured. Still took out one of my attackers though.
