I've been using macros for about one and a half year now for PvM (3 macros total) using ghub software. Never noticed a thing. Idk about the fletching idea, never did it, but in theory the latter (keystrokes record) should be hard to detect, as long as you don't push your luck
Oh, unlucky. I heard rumours about there being a different one that hasn't been patched and figured it would've been worth asking anyway. Assuming that one never existed then :(
