Not really just don't feel the need to elaborate on this anymore. In my opinion it is a needless change, it does not go with the theme of sm, if we are accepting a world of battling robots than this is counter to that cannon, and finally given the graphics of sm it would simply look like a blue mass going up to your mechs knee since water is actually quite difficult to render. Probably kill your computer trying to render it if it has problems now.
yeah anyways focus on other the other suggestions...
