Monoliths are like Land Raiders armor-wise, but no one says Land raiders are cheese- I guess it's cause of the Gate, but the Gate is a blessing and a curse. First off, you can't chain teleport- like with a VoD and a Gate. Second, like others have said, lose the Monolith and all of your reserves DIE. Third, the monolith is expensive. This is more of a problem than it seems because it is a MASSIVE point sink. While you are waiting for your reserves to become available and running from Broadside Battlesuits, they will be mowing down your troops and phasing you out. Know your weaknesses and you will know your strengths.
