The most important question this has raised in my design and development process is "Should there be large Centaur tanks"? Obviously, but should doesn't necessarily mean they'll be in the final product because at some point the piloting mechanics conflict with eachother.
Basically, there's a god at the intersection of an HK-Tank from Terminator 2 and Blade Wolf from Metal Gear Rising that, while perfect in all ways, isn't necessarily fun to control.
