Unbelievably stupid not to schedule around $100k+ tournaments. There is a hugely important - and very close - match happening tomorrow between RunAway and KongDoo Panthera and it will just be a guessing game between the two. They won't have been practising extensively in PTR, they haven't had anywhere near enough time and were told the changes would not go live in that form.
Then there's the playoffs, and there's no guarantee whatsoever that the teams who were good in the previous patch will be as good in this one. Look at NiP, the difference between the two patches was gigantic - in one they are a tier 2/3 team in Europe and then suddenly in the next they're one of the best teams in the world. There's very little legitimacy to the teams who made it to APEX playoffs now, they'll have to scramble to adapt as a lot of their preparation, practice, and comps are thrown to square one.
The PTR has not been tested enough and they have done only one iteration of it; the PTR was even advertised as major changes that shouldn't be expected to all go live. It blows my mind that they've just shoved it live and fucked an enormous tournament. It makes me so frustrated to see these basic mistakes. All they had to do was hold off for just over two weeks, making some small tweaks to the PTR based on feedback in the meantime, and there'd be a far better reception and they wouldn't have fucked the biggest global tournament so far in Overwatch.
