It's way slower than the normal one so it's not good for general mobility
It's inferior to the tank in combat, less versatile and at the same tech level so it's not good for killing nests either
For some reason it has half the shooting speed of the handheld rocket launcher which makes it specially bad for combat, surely this was not intended?
I honestly just wanted an armed hovercraft that can deal with the odd biter attack without having to sacrifice HALF of it's speed to do it, it's an incredibly harsh tradeoff for a terrible benefit, i just don't get it.
