With so many issues right now, the easiest and quickest fix would be to bring a 5-players entry level dungeon + remove ilvl requirement for all dungeons.
Normally, I wouldn't mind a grinding patch but when you hard lock the very little content this game could offer behind ilvl and gears only last 6 months, it just kills the game. Maybe it is the aim of BHS and GF is just trying to squeeze what little they can more with constant bonus 70-80% TT events.
I couldn't agree more with Rosa NA, probably no point trying to save this game and best to just leave it die, especially if the developer & publisher doesn't want to save it.
