>Another is hit locations.
This doesn't make any sense. A mech has to stand upright, while a tank is much smaller. Because of it's smaller profile, the tank should be harder to hit anyways. That is, if a mech has 8 places to hit, a tank should have 4 places to hit and 4 places to miss.
>Third is motive damage. Tanks can take damage to their motive system relatively easily, making critical hit rolls from normal damage. These hits can quickly slow a tank down, or worse, immobilize it, both or which are basically death sentences in Btech. For a mech, you have to punch through or use special weapons in order to achieve critical damage, they can't be hurt nearly as easily.
Mechs have legs, though. It's not like you can't armor tracks and give tanks superior suspension if that was required.
I mean it's just glaringly obvious to me that standing upright is a huge disadvantage because it makes you a gigantic target. Your surface area is fuckhuge too, so to get the same protection you need MUCH more armor than something like a box, or else you risk getting your legs blown off by weak weapons.
>The movement is one thing. Mechs can go just about anywhere, a lot of vehicles can't.
This is the only real advantage I see.
However, why not make your mechs 4 legged, since mobility is pretty much the only benifit. 2 legs won't really help you get down a steep mountainside.
Also, tanks should be capable of using jump jet type features as well to cross terrain, though they should of course not be able to jump as high or as fast or as far due to the worse suspension. However, they should be lighter than mechs due to the reduced need for armor, so a 50 ton tank should be able to do the job of a 70 ton mech, anyways.
