I agree, few will be crossing the field very often, but having the capability to do both the bump and bridge can be very important in the occasional situation

Pros: Can cross the field quickly, can play better defense, can get around defense more easily, faster crossing time, more appealing when choosing alliances

Cons: Heavier robot (if you use separate mechanisms for the bridge and bump), takes more time to develop and build, more expensive

Overall, it is good to be able to cross the bump, but it would probably be better to focus on other aspects of the robot such as shooting (unless you plan on doing hardcore defense, where it can be good to be able to quickly go over the bump)
