Our CM, Kitana, while still in Kharkiv, was able to get some info on this. Gotta admire the determination. 👏
So, this was removed intentionally, but not necessarily permanently. It may or may not appear again from time to time, so keep an eye on it. An item is planned for this functionality, but these plans are obviously not developing now as intended, it might be a while until it's implemented.
Why remove it "silently"? Because it was not a regular bonus nor included in the description of the Battle Pass. So, it's considered a minor change.
Personally (i.e., not as a mod), I'm a bit confused: travel time to Prizes is usually very short and I can see why the removal of this would be considered a minor change. Why is it so important to you that you'd spend $10/mo on it?
I'm asking because you said you won't buy Premium Battle Pass anymore, since it was removed. That's fine, of course, but it kinda implies to me that this feautre alone is what you're paying $10/mo for and I'm failing to see why would it matter at all, let alone be a dealbreaker.
