Nothing ironic about that. You'd have to separate your ideology of camping into 2 different approaches.
Say I get a killing spree (camping or not), my ordnance meter is full, and I spawn rockets 5 feet away from me. That's just great, isn't it? It wouldn't matter if I was camping or not because I didn't have to time out when the next fixated spawn would happen, and I didn't need to relocate to that specific part of the map.
The reason this is more useful and beneficial is because they want to make sure you get your reward for getting a killing spree. If you were meandering the map, getting kills towards your meter, and quickly wanted to hide in a back room and spawn your ordnance, it almost seals the deal. This doesn't matter whether you were out in the fray or just simply hanging back and picking people off; however, if you are playing a competitive game where people understand the layout and the spawn points, they're going to keep a general position around said power weapon to ensure that they can get it before you can.
Think of it as throwing a positive wrench in the works.
