We’'ll probably leave this up for a few days. A week at most. We want to cover a few “prime times” in each region as it will help with data collection. For example, at the time that I am posting this it is prime time on the east coast in the US.
Once the card comes down, the next changes coming to it will most likely be balance changes (things as extreme as 3-2-1 will be rare). I would expect the card to come up “every few weeks” and stay up for a few days, if that answers the question.
A bit confusing… but the PTR will also be coming up, possibly even during the duration of this current experiment. There are certain things that can only be tested on PTR and cannot be tested in an experiment. For example, if we wanted to make a change to Mei’s Ice Wall collision we would need a PTR for that. Purely random example… um yeah.
