I guess there are different opinions on what constitutes a "cheese". In my opinion, finding a spot where you can hit the enemy but he can't hit you is "cheesy". I don't think it's cheating and I don't judge anyone for doing it, especially since I do it whenever possible. Exploiting a glitch is more than cheesy, it's cheating, but I'd still do it to get through a particularly difficult nightfall or raid. BTW - my buddy and I also discovered that in the section with the tank, you can jump up on the cliffs at the back of the map or on top of the roof over the opening to the room with the interceptors (portable tank thingies) and hit the tank w/ snipers and the tank doesn't fire at you at all. It's not a glitch, it's in-bounds not out of the map, but it's cheesy because you can kill the enemy w/out it being able to fire a shot at you. Now that I've found it, I'll use it all the time.
