Having played Railgun a few times I often found it was easy to reach the MG nest if you thought about your movement carefully, but once you start getting near the choke point of the flag you get cut down more of the time, so instead of helping the you bring the fight to them, why not bring it to you? :D

In this example the flag could be dragged out of the inside of the depot and onto the space where there used to be an MG nest, this would also elimnate the problem of the MG in situations where clans use it on defence.

This one I'm all for and can't think of any reasons to not try it!
