This, and the good old fame trains require no skill, which is why I don’t consider stars to be an accurate representation of one’s skill. If you got stars by completing difficult challenges, for instance being able to solo a rather difficult boss, or finish a dungeon in limited time, then I’d gladly accept most white stars as good at the game.
This reminds me of something another game had. In that other game, you could recognise a player if they had a specific cosmetic set that could only be acquired by defeating very difficult, endgame missions for which you needed excellent strategy, aim and coordination. As so, people with those cosmetics were respected as elite players.
However a cheap strat was found that made these missions trivial, as long as the player used some elaborate glitch. In a matter of days, these cosmetics were obtained by players that were really bad at the game, but used the glitch to get those anyway. What was originally a mark of respect was now something you could get regardless of your skill. Sure, some of those people are very good and got those legit, but there’s no way to tell them apart of the newbies that exploited the glitch.
Replace those cosmetics by the white star and the glitch by cheap methods like fametraining and LH raiding and you get a similar situation : what was supposed to be an award of dedication to the game and ability to keep a character alive through a difficult game is now awarded to any player that has the ability to simply follow a group of players.
TL:DR sure some white stars are worth respect and got this title for a reason, but if anyone can get it without even getting good at the game then it doesn’t mean anything anymore.
