>>31659802Broken is the sense that Flying is an insanely powerful attack type, and you need to be really careful who you give it to because even Drill Peck on every Flying type would break the meta.
Look at Talonflame. GameFreak gave it a measly base 81 Attack for a reason, and even that wasn't enough to balance it.
Look at Mega Salamence. Aerilate is insane on it. It wouldn't be half as bad with something like Tough Claws or Adaptability.
Look at all of the mons that were banned from UU because of Z-Fly. Look at stuff like Landorus-T, Celesteela, and Gyarados, whose list of answers basically halves.
