I make it a rule for myself never to have a wedge or pushbot, but I see no reason to ban them.

Yes, I think flippers and spinners and specially axes and hammers are far more exiting, but seeing a storm II slamming a robot in the wall without his lifter or a Bonx doing likewise in the feather department is not my idea of boring either.

Having a wedge or a box is not the problem, how you use it is the major issue.
