I started playing brits.
The comet feels like what the tiger somewhat should be. It wipes infantry left and right, has overhelming speed and decent at capability and armor.
I dont know the numbers but this tank feels to be the most versitale tank in the game atm. Even though he is a stock unit.
IMO comet is what the panther should be (maybe panther could be slightly better at than ai, while comet should be maybe more ai than at)
But yes it is a great tank, similar to pershing imo.
