Past level 50, I used all my accumulated enlightenment and now a master writ only give me 17k xp - it was over 100k just a few minutes ago, then 60+k, and now it's not worth to spend writs anymore.
What should I do? Must I wait 24hr before leveling again? The usual 150% scroll and training sets etc are just too slow without enlightenment. Any option other than spending 4 times more effort grinding, questing or using writs?
