Why is nexus required for half the week's DC's??

Kind of common knowledge nexus and labyrinth are probably the two most hated dungeons in entire game (basically anything with that stone slab tileset). Did NCS purposely pick the most boring dungeons to be part of DC's? For people who don't touch PvP they have no choice but to do 4 of the 4 PvE dailies, zero choices there. Out of 7 days in a week, I recall nexus being part of 3-4 days' dailies... wtf? I mean that place drops pretty much nothing useful other than maybe an ugly outfit... and it's hardly a "challenge" for the people now with everyone and their neighbour having 600+ AP. Why not put VARIETY in the daily rotations? It's like your game has a total of 5 dungeons. What happened to DT/EC being dailies? Hell even the boring 24m grindfests aka grimhorn/e.fleet/NSH are less boring than nexus/labyrinth/gloomdross, at least it's open world not some "corridor simulator" or "babysit some crocodiles taking an hour casting alohomora on an orb".

Hoping these shitty dungeons will be removed from DC's for next patch or at least more VARIETY put in place... this is just one of the MANY things that makes you wonder if the marketing department at NCS, if there even is one, are mentally competent. "We've got like 20 dungeons for the game but let's just force players to grind the same 5 everyday! And make sure they're the shittiest, most boring ones!" -__-
