That pretty much covers it. I’d like to be able to buy maps with gems, personally. I’m probably in the minority that really likes the Treasure Hunts, as much or more than the base game. I have a pile of gems, bought the armor I wanted, and aside from using them on gem/event chests, they just kind of stockpile.
I don’t know if there’s already a rouge conversion/equality rate that would show how much glory a gem is worth, but if it were like 10 or 15 gems per map, I’d be all over it.
