The Tank Destroyer's look great, would love to see them in game.

But given that TD's have less armor than MBT's and they have no secondary weapon on a swivel (or indeed bring it's main gun to bear fast enough) that can deal with the overwhelming amount of Anti-Vehicle infantry weapons, that already make driving an MBT or Lightning an extremely brief occupation for most of us, render these vehicles useless.
