Maybe add like an 'add time' option to an instance. Maybe have it add like an hour for like 100k platinum(I have a free waypoint maker so it doesn't really matter to me). I only say this because I hate when I am clearing Abyss or Loping Plains and see the dreaded 15 minute message when I am almost done clearing or have a bunch of names up still. Maybe you can have like a 3 time limit for that instance.
