Turn Praetorium into a trust dungeon or solo duty. It's supposed to be a climatic, last ditch raid on the villain's fortress... only for veteran players to ROFLstomp all of the supposedly "elite" soldiers and "menacing" robots. And then the newbie player gets left behind while everyone else rides up an elevator, and then a cutscene begins and suddenly the newbie player is being asked to teleport to the boss, and by the time they load in the boss is 50% dead, and then immediately another cutscene begins... etc.
