Just as an example:

SPLINTER EVO
Weight: 100kg
Power: 2 750w motors
Weapon: Axe and clamp
Strength: Grabs and won't let go
Weakness: None

If you see the robot in real life, you would see that its weakness is being flipped. Therefore we should keep weaknesses, because they as close as we can get to seeing the other person's bot and noticing their weaknesses.
