I can imagine why a hideout would not be the retained solution, because it does not allow to see other players’ mtx.
But having a single point of access to the various endgame NPCs and then to a monolith directly at level 100 would greatly streamline the game.
Currently we need to TP to the CoF or Merchants faction, then Woven faction, then go to end of time timeline, retreive the monolith we were farming, then select again and again level 100, then select an echo …
In the long run it is painful and the feeling is clunky.
Also sometimes there is a bug, you finish an echo open your portal, and you arrive in fall of the outcasts monolith instead of the one you were, and you loose the reward in the process, and you need to TP again to the desired monolith again, select level 100 again … painful.
