Distance plugin doesn't do shit that makes what he did anything less. That's it. It's not hard to gauge the distance between you and a mob.
If it makes such a little distance why use it.
Certainly there must be a reason.
If it makes no difference, then it should be just as easy to say do it again with no windower macros, no distance plug in, and no TParty to see mob's HP% If it "doesn't do shit that makes what he did anything less," as you so eloquently put it, then why did he use them?
I wouldn't call it a "cheat" but it does make things easier. It lets you see things that the original design of the game did not allow you to do. In some people's books that is defined as a cheat. Apparently it isn't in yours. While doesn't make a difference in the nomenclature, it still affects his playing. But if you insist that it really doesn't make any difference, then have him do it without them and post THAT video. I look forward to it.
