That's the thing about a grind though, pace yourself, you burn out of course you're not gonna have fun. I can feel myself burning out from the light portion doing the same boss over and over again can be a bit tiresome though it is a nice change of pace from when I was doing dungeons to gather alexandrite lol.

There are other games out there, if you burn out play something else, come back to the game later, you'll feel refreshed, anything gets boring if you do it over and over again.
