I've been saying this for a while already, tanks and armor are quite outclassed right now and with the new score system, people will literally suicide over and over to get armor kills, giving enormous points to the AV infantry. Buff tanks. Make them significantly more difficult to obtain as often as they can be now. hell, give them a 1hr cooldown, but buff them to take more hits or give other methods of damage mitigation like the vanguard shield, or the VS evasiveness and magburner. Make them scarier, but far, FAR less in number.
