So you think clicking 1, 2 or 3 is more tactical than hitting 1, 2 or 3 with your finger? If you think keybinding is anywhere near what botting is, it's pretty obvious you haven't keybinded before.
I think you are mixing binding and macroing up...these aren't the same thing. Binding is no more automated than clicking. You choose the spell you want, you click or press it.
Again, I really don't think tactical means what you think it means or you are actually considering what you are claiming.
