Is the Light Tank the new Main Battle Tank

Ectar: I feel any tank class being "dominant" depends completely on the map you're playing and the team compositions.  In open/hilly maps mediums or lights with good gun depression are more likely to triumph where as in towns heavies and TD's that can use their armour will come out on top.  In-game there is no real "One tank fits all" situation, light tanks have advantages with speed but their guns still will never has as much alpha as a heavy and they will still never be able to take shots like a heavy. When you try to break it down into one on one there is too many variables and set circumstances that you then have to add in to make it favourable for one or the other.
