The only time I can say I fet like gambling was acceptable in a game was in the way that it was used in FONV, but that was a solo experience with no outside influence from other players having gained in game items or buffs from it. It was entirely risk free aside from running out of caps. These days developers are generally pretty damn greedy, (Not saying FDev is, but many are) And will generally try to slip in any MTX that could keep thier players hooked.
Ten years ago it wouldnt be a bad idea to have some PvE gambling concepts in a game, but since the MTX turdstorm, it's very risky for any developer to stat going down such a line because it will immediatly be brought into question by the games playerbase. People will become suspicious very quickly, generally not a good thing for a game like this one which has a fairly dedicated fanbase.
FDev would do well to note the current issues in the industry and do thier utmost to avoid them IMO.
