Very helpful comment.

If you were familiar with (and actually playing at a top level at) any other competetive game, youd know that this is only **technically** correct.
It is not feasible nor reliable to hit a flying AOE Bird with 250% movement speed with Bebops hook or any other stun for that matter. Especially not during a teamfight, where you are already being stunned and shoved around by other heros.
In fact, this combo is so strong, that playing anything else would decrease your chances of winning significantly. Hence no counterplay.
