Honestly, we never had an issue with it. Heck, only time we had down time was when fasteners backed out into the frame (and yet we still won matches at an offseason just using it as a brake). In my experience, it is better to have the suspension on the traction wheels since then you don't loose contact with the ground when pushing, while having suspension doesn't fix a cg out of place. In addition to that, it seems that having the mecanum wheel on the end of the pivot is worse for survivability than a traction wheel that is only in use rarely. Plus, you should make the traction wheel as small as possible to cut down on weight by making the overall module smaller.
