One of the big complaints about Mabar is that there is no xp for running it. Unlike Crystal Cove, where the kobold event is worth a fair bit of xp, or Festivult and Risia where you gather the event coins through normal gameplay, the Dragon event in Mabar is essentially worthless once you have obtained and upgraded whatever Mabar gear you wanted. Many players achieved this goal in 2010, 2011, or 2012 making this Mabar essentially worthless beyond 3 dragon encounters spread over 3 days.
Recently the daily dice were changed so that you obtain exp stones from the dice rolls.
I suggest adding those xp stones into Mabar on the motes vendor on a 1 mote per 1 xp exchange, in multiples of 100 up to 1000, and then multiples of 1000 up to 10k.
100 motes = 100 xp stone
200 motes = 200 xp stone
etc. up to 1000 motes = 1000 xp and then
2000 motes = 2000 xp
etc. up to 10000 motes = 10000 xp.
Players with thousands of motes sitting around and no interest in the garbage consumables like pumpkin head bombs would then have something useful they could spend their motes on.
