Only half exp from ores and/or fishing. We still need ways to get it if a shop type thing is brought into place

 

1/4 exp from ores, and 3/4 exp from fishing along with increasing fish prices. Keep spawners in the mining world the same, and increase spawners exp drops in the nether. exp in the end worlds, if that is ever added, will need to be nerfed greatly too. This will allow players the opportunity to regulate he market by destroying/farming/hunting spawners, which would be the greatest source of exp if my suggestion were to be done. Make something else to spend exp on too... There is way too much exp in the economy for a nerf alone to make any significant change in the price of exp.

 

We just need more options to spend our exp on, I think all exp gain should remain as it is. See how the exp market does after adding more options to spend it on, if anything needs to be adjusted then do so after you have hard results... No use in playing this what if game, just do it and see how it goes lol

 

Turning regular xp into mcmmo would be quite cool. I think it would take tons of xp out of the economy :p
