Gv/Grams camps are a part of LOTRO PvMP. If they made a no gain zone at both of those locations there will still be camps. Why is this? Because it's still kills. It is still PvP.
To restate something that was already said in this thread, camps do not have to happen if you do not want them to. You can move around, map, what ever to get away from it maybe take a keep and try to force a fight there. Yes they can be VERY dull and boring but I personally do not mind them that much. When you camp Grams you tend to get some Creeps to come out. When you camp GV you tend to get some Freeps to come out which both leads to more/better PvMP.
Of course, it all depends on what people you have out. Scrub players tend to not be aggressive therefor more boring to fight and as for that problem it has to do with the server not the system. All in all, I can sum up my response to your comments about camping main hubs in just two words. No qq.
