I disagree with you 100% on this one, if someone ruins something like this, its the playerbase taking stuff like the old events for granted. Its definitely not ruining anything in this game, if something is ruining anything in this game its people with 0 knowledge of the high end raids getting stuff from that, just like sealed weapon materials etc etc etc. THIS is stuff that ruins the game. If you dont run the dungeon, you shouldn't get the materials of it, simple as that. May be an unpopular opinion but thats how it works.
Edit: Also not "one game" , but ~ 75% of the MMO's or Multiplayer games in general have stuff like this, hardmode = better rewards. We even got this right now in terms of hardmode dungeons with outfits and noone cries about that LOL.
And whats so bad that people which dedicate a lot of time to the game or money (LOL, im really saying this) in certain cases like trove or whatever, gain something exclusive? Its so damn hilarious if you think about it, complaining that people which are at the top ladder of Progression getting something unique for them, how dare they get something good for their efforts.
The only thing thats still exclusive till this day is the Founder - Master Pack Titles and the costumes of it (even though we got the reckoning reskin atm). Stop crying about the fact that there are sometimes events which are just not made for your gear. This is a good decision and i think they should do more of those events where lower plebs get easier dungeons (like in the past) and players with better gear get their own and therefor maybe 1 costume or smth unique.
