I get that, and can agree to a certain extent. Although I feel like making a team around Pidgeot is so simple, [Insert Aero Counter], [insert Ground type].The main thing keeping Mega Pidgeot from going to S is the fact that it is utterly helpless against the best and most used Pokemon in the tier, Mega Aero. If Aero wasn't around then I have no doubts bird jesus would be S rank material, but just the mere presence of Aero is what pushes is down to A+.
I do respect the reasoning, and won't bring it up again unless Aero moves up.
