So, right now we have like 10 groups trying to get full for fractals 1 ~10, cause people must be on same level than the desired fractal dungeon set the group is willing to run.
That said, 40 players will have to wait for one last person, and that looks just like , on every mmorpg, waiting a lot for healers. So, removing the trinity you removed the player queue time, but adding fractals you just re added a very long one: the quest for the last fractal lvl x player.
So, why not making the fractal a debuff and buff for players, and everyone would run together, but with % chances on itens and stats changed by the amount of fractal runs each one did.
Or we will have 20 groups trying to fill their last spot.
