Ah, See, you said it yourself, Crosshairs and other ui TECHNICALLY
Are add-ons, And yes i understand, some truly are bad, But its not often you get really crappy ones now is it? i mean sure, occasionally you get a guy who has no idea what he is doing and uses MS paint or something *Coughcoughnerdycoughcough* (Lol, but i fixed em :P)
But you can't HONESTLY say every crosshair ever posted is crappy, I will agree with most people, My crosshairs aren't the most creative or even the best for that matter, but, they aren't the worst you ever seen now are they?
