Mixing up imbalanced mechanics with player to player scoring and balance makes about as much sense as a why a Warrior class in any RPG has to fight in close combat, rather than stand back and heal.... you know... coz... fckn WARRIOR ?

Its not supposed to be easy, but "balancing" the game with broken ass mechanics is just lazy of the highest degree and never bodes well for the games longevity. With the amount of games to choose from people will naturally shift to better products when they detect negative attitude from devs. This hits all the spectrum of games from AAA titles and highly funded MMOS to and especially for browser games.

And no a leader tank one shooting you tanks aint balance.
