You got to be a part of their super secret “data” and/or “feedback”.
This is just an easy thing that people say. This is like saying “War is wrong”. Give you lot a Nobel.
If it didn’t matter it wouldn’t be a competition with a monetary reward that Blizzard refuses to make any tuning changes while the competition is ongoing. Tuning changes which then appeared with major nerfs the moment the MDI concluded… what a coincidence I guess.
At most it shows class specific strengths and strategies outside of normal gameplay. At least it shows cheese certain class mechanics can preform. In that entire range, nothing is available to Brewmaster to give any advantage.
Just another point of argument you see the same thing in raid, at minimum the last two expansion’s. They don’t tune mythic raid around you or I, they tune it around the race to world first. Meaning they tune for the top play, not the middle. They expect a majority of their players to fail. If the RWF brought 6 ret paladins, what you think Blizzard is going to be like “Oh that’s fine we don’t need to balance that because that’s not normal raid composition”. No, it gets nerfed.
