Both Light, and Light Ewar would need speed tweaks for this to fit into everything correctly. But this could be done in increments with the end goal of slowing down mechs and heavy mechs. Done though select speed ups of lighter bots, and small incremental slow downs on heavy mechs. Mechs, and Mech Ewar falling in the middle.
Why do want it this way? This opens up Mk2 bots for different things, and if these are accepted within the community I can take those ideas. Those that latch onto Zoom's original specialized bot ideas, and move them forward with balance suggestions and newish bot boni.
