For outdoor play, you can see the bb trace to your target just like paintball. I have a red dot but rarely use it unless the target is in the shade where I can't see a good trace. I would have shot you while you are wasting your valuable milliseconds trying to sight me in your red dot.
Red dots are also good for low light indoor play and very practical.
The other thing you have to consider is parallax issues with airsoft red dots.
