If LEDs are so important, why dont use them on featherweights aswell? They coundnt be used on antweights for simple weight problems, but seeing as some featherweights are as powerful as middleweights, they should really be used in featherweights aswell. I agree with some of you that a LED should not be a main way of telling if the robot is active or not, but it would make a useful way of seeing if your power is on at the start of a battle.
One solution would be that someone makes a removable link that is much clearer than the standard red links, one that makes you clearly see if the link is in, or not
A robot is never really safe, as there could be fused together wires inside the robot, due to high currents. This would still make the robot active. There is NO way at all of truly telling if the power supply is on/off, so we should all look for common sense in most tricky robot scenes.
