I have no issue with battlepass being paid or free. I do think it's an issue for Bohemia to do both and to not address it. Kinda like when the game went from paid to free, they at least offered a compensation for those who paid. Whether it was adequate or not is a different point, but at least it was addressed. It also seems like an unwise way to do a roll-out of a new feature.
It seems like a legit point of discussion, I see no reason for a moderator to lock the discussion as long as the language is reasonable and discussion doesn't devolve into trolling.
