Revamping treasure maps

[Seeya]

In my opinion.. there should be a complete revamp of treasure maps. They're good for experience.. but I think it's an easy way to get more drops into the game along with the rewarding experience. I had a few ideas.

perhaps, add a treasure chest in higher level maps, or randomly in lower level maps (depending on the level, easy maps have very low chance of having a chest.)

I'm saying a chest instead of a randomly awarded drop in the end, because if you had obviously 8 people entering a map all to have a chance of a reward at the end... bit much.

Chests could give items, not highest tier, but decent. e.g. Belt of Crystal Heart, Ring of High Divinity, on a very low-chance scale. The normal reward from a chest could be 15 sapphires or 5 diamonds.

An easy way of getting necessary (to some people) items into the game, at a steady basis...

Anyone else have ideas to update treasure maps?
