I kinda wish ra2 had fall damage. when I toss a robot 30ft in the air it makes me a bit sad that it takes -20pts and is totally fine. in real life that thing would be toast.
ra2 does have fall damage. you notice it the most in stock where the components and armors are weaker. it's still ineffective, but i've seen more than 1 pixel on the armor HUD go down when I've tossed bots across the arena before. in DSL or especially ironforge fall damage is a complete non-factor.
GTMCS1 tried to fix this with their arena by having a damaging floor. that made all sorts of other problems.
i've got a fix. nerf the HP of all parts in a mod down by like ten times. i'm serious. fall damage in ra2 is basically a constant coded into the exe, the only other thing to do is reduce the HP and DP all parts by a large factor and then by design fall damage would rise dramatically. it wouldn't affect fights since all parts would still be balanced with each other. if you get DP values and such too low there might be rounding issues and stuff but the main theory is sound.
I doubt any mod will take advantage of this, just thought i'd mention it.
