Everyone has made valid points for both arguments, I can say I watched teams use mecanum in 2012. They get no traction on the bridge, and with that being said, trying to breach the tower would be alot of work. It would be possible since there is a little lip that might catch the wheel and stop you from falling off.

The argument that mecanum isn't good defensively is only partly true. It does have an advantage when playing defense. The object of defense isn't always to win a pushing match. If you are trying to just get in peoples way or slow them down, mecanum helps.

We had mecanum in 2014 and we mostly stuck to defense as we had multiple unforeseen problems, with little time to repair. We would get pushed around a bit, but it also meant that teams were targeting us instead of the ball. Plus with mecanums maneuverability you could easily strafe away from defends, or strafe into shots to block them.

That being said the only defenses mecanum could pass is the Portcullis, the low bar,possibly the ramparts if hit with enough speed, and the C defenses.

But theres also the option of other wheels:
Pnuematic
Plaction
Hi Grip
The Gray ones (Slick?)
Colson
Banebot
Tank Treads

There might be some I am missing, and i didn't count omni because they have less traction then mecanum.
