This is just absolutely outrageous! This is why balance is a myth in this game. Once the shop offered me an Mk5 tank (Hull, Turret, & Protection) at Warrant Officer 3!!! This guy is basically a Colonel but at Warrant Officer 5!!!

In short, defending team is much better off than the attacking one. Assault mode on certain maps is UNBALANCED. This is due to the defending team is highly favorable where their base is in the corner or the edge of the map, meanwhile the attacking team have to carefully attack their base or whenever they die, the defenders get one score. However, this could be easily fixed with bringing the defending team's base to the center of the map like the one in Aleksandrukhov or Wolfenstein so the attacking team has much more chances to win the battle.
