Nope, it's not. I just made sure I would not get an advantage because of two bugusers on my team. Bugusing is - in fact - against the terms and conditions of Xbox Live. If you feel better after this.. I also reported this two guys when this match was finished. Hidung on a spot where nothing can hit you is bugusing. It's not "taking cover", it's just bugusing. Wait.. I have another exsample. I don't know how this PVP map is called. It's the one were you can see the traveller and which plays near our nameless city. I got three times killed by someone. He was playing as a hunter, somehow jumped over a cliff but survived. You know this spot right besides the cliff where heavy ammo spawns, right? Follow this way to the end. He sit right below this way. I saw on my radar that he has to be there, so I looked for him. He killed me through the floor, three times.. before I gave him a sticky grenade as a present before falling to my death. That's the same thing. He could melee anything that's on the way above him while anything above him couldn't even see or hit him. I'm sure you would consider this as bugusing, right? In this case.. doing the same thing against npc's is bugusing as well.. and that's what I was talking about.
