Ah yes, but with THOSE points, all valid, I think perhaps we should conclude the weakness stat is used as an empty shell most of the time. Often the stat says things like low torque or no active weapon or other things that can be seen in the rest of the stats already, while indeed in your example the weakness stat would actually add something to the description of the robot.

But Im also gonna say alot can be said in favour of Andy's and Kody's arguements, the stats should give enough information to come up with a proper counter strategy.
