I love shipment HQ, though I must admit that I rarely go for the capture on that map, and when my team is up by 50-60 we stop going for it at all, so we can get more kills. Then again that is with my team, and we own anybody. There are a few other HQ's I refuse to go for, like the outside one on vacant, or the middle on wetwork, but generally I'm all over the HQ trying to cap it.
