I frankly don't care about any of that. This is a simulation. If you can use your abilities and the environment to make a tough battle easier, good for you. Doing so is perfectly legitimate. Changing the underlying, fundamental rules of the simulation to keep players from using their abilities and environment is NOT legitimate. If Bungie wants less sniping from the perch, there are any number of ways to do that without violating our willing suspension of disbelief. This was lazy, ham-handed, and inexcusable.
