Mavic seems to rotate very easy in the air?

I was out flying my Mavic today with absolutely zero wind and when it was stationary in mid air I found it was very obviously panning left as if I was making it move with the controller very slowly. Is this normal? Both my from props have had a very slight brush of a wall when I first flew it, they are not damaged or broken but you can visibly see where some paint has been scraped off the propellers, other than that they seem like new. Would this small defect be the issue? Thanks
