Many wizards all over the spiral can no longer gain experience, but still have quests to do to get new spells, or a new pet, or a new badge. For all the players that have maxed out their exp pars i think we should be able to translate the exp we receive into gold.
Another use would be to have our energy refill when we gain a certain amount of xp after we get max. For Example...After max out there would still be a bar but when ever it fills we get an energy refill.
well i dont think thats such a good idea, because a lot of the quests give around 15,000 XP, so maybe a certain fraction of the XP could be turned into gold?
