add a couple of dungeons for people who just finished the game so they dont have to grind the same dungeon over and over until they have good enough gear to move on... also maybe you could award extra tombs for good performance during dungeons... also award tombs for beating lvl 50 boss fates... add new questlines that award tombs... any other ways of awarding tombs that would help people do other things instead of grinding the same dungeon over and over.
