Nice suggestions but they've been repeated ad nauseam on this forum. After an embarrassing amount of playtime on this game I've come to realize that Destiny PVP in particular will always have significant lag issues. Now obviously every online game will experience it in one form or another, but in my opinion there is something going on with the game engine that is creating it's own inherent delay that is exacerbating the lag which we experience. My theory is that there are too many client side checks from all the nova bombs, sticky grenades, crazy laser rifles, exotic armors and all the modifiers that go with them that are create just enough of their own delay that, by themselves, would barely be noticeable, but when coupled with the usual latency the occurs in every online game becomes problematic.
