i think the problem is:-
Wedges can be entertaining, the good thing with them is they can take a full spinner hit, which cause lots of sparks and bangs,but keep going, but like flippers if their are too many they are dull.
also their trusty rambot that never lets them down, its cheap to maintain and gets them further in competitions.

i wouldnt be bothered either way, if the rule became compulsory and you wasnt too impressed with having to have a active weapon, its easy to add one to any robot if you think about it (doesnt mean it has to be effective)

Perphaps people should be incouraged in sum way to have a active weapon?
