Another con that nobody mentioned: corner intrusion. You have a perfectly legal robot, designed to flood the corner goal, and you have measures not to go in at all, but you have bumpers. You go to the corner and start flooding it, but then somebody shoves you in. You get DQ'd, just because the bumpers are 3.5" max and the rule is 3". Now, that was about the only game design issue, but it was serious. I'd like to see bumpers next year (again, nothing prohibiting teams from using ones other than the design, as long as those stay in the box), but with the field designed to allow for them.
