100% that is absolutely not the first or even second thing I think about when it comes to Gloomstalker, lmao. Also we know for sure Larian COULD have done it because of how some other things are implemented, they just decided not to. Overall I'm fine with it, and that's even assuming it's accurate if you're looking at release leaks. As far as we know there hasn't been any official news when it comes to subclasses, I don't think? So you could be looking at information long since out of date.
For me it is the only reason to play gloom Stalker subclass, the dreaded ambusher is icing on the cake , but mostly to me its only worth 3 or 4 lvls in to gain the invisibility part of umbral sight.
