They just don't want to force people to play PSO2. Thanks to PSO2 and NGS being the same game by technicality, many of these things would "force" any new or returning players - or people who just don't want to play PSO2 anymore in favor of NGS - to have to play an older, less active game just to get items and currencies for the game they actually signed up for, which sounds like a great way to turn these people off.
thats great. they shouldnt force us to play NGS if we want to play base. Its just as stupid.
