Just an interesting minor idea, if you have legs that are capable of jumping, they should be able to fly in the air, but stay on the same spot when using the 'Stomp skill', and crush the ground, instead of lazily lifting one leg up, this of course should give them a small damage boost as well.

What do you think of this?

Sword>stomp

I don't think I would like a mech jumping in one place because there would be no point for a stomp option. Why stomp an opponent when you can just jump for more damage?

I tweak. It would good if certain legs could do this, requiring energy and heat to use, and only have a limited amount of used (like twice). However, all swords minimum at the level the special stomp effect is offered would have to deal more damage than it. Otherwise, it would be too dangerous.
