I suggest not waiting, but awarding the spot through additional games. It wouldn't be fair to Protos, because his rating on HeroesWorld is the lowest, as he hasn't played here before.
Although, for the future this idea could be great — it would increase the value of the rating, but it needs to be announced in advance.
I'm waiting for the official "green light", "ready, set"
In half of the groups, it's still hard to tell what the results will be. Transitional games between players from different groups will be more fair and unambiguous.
