Per usual, I am speaking on behalf of myself, not the Gen 9 OU council, so please direct all criticism towards me.
We are now at a point where BW PU, Monotype [Dragon], and even AG ADV + Mega Rayquaza have all banned Gen 9 Baton Pass with massive amounts of support internally, but OU did not despite receiving by far the largest and arguably most justified outcry from their players.
As a member of the Gen 9 OU council, I feel it is my duty to make the tier the most competitive for my player base and, with this goal in mind, it is clear to me that this is not how things should be. We should make an effort to reconsider the situation promptly. Now that you've had time to reconsider your decisions, I am hereby declaring a blanket ban on Gen 9 Baton Pass, effective immediately.
