I'm a big fan of the DMR but even I agree that that rifle needed to be removed from the spartan hands so early on in the Invasion game type because it made it nearly impossible for the entire elite team to get to the objective as a group to fight it out with their close range weaponry. Theres still gaping problems in there such as the fact that a Ghost can kill the Scorpion with only around 20 - 50 seconds of sustained fire on the rear armour. If I look at the two tanks I'd have to say that where the Scorpion has power and traverse the wraith has the defense and also due to the boost speed.
