This morning i was lvl 40…i played for something like 24 hrs in total since the release.
Just avoid the fact that it’s really hard to have fun…when you have to grind as a crazy man, instead go adventure with your friends.
This morning i saw some people at lvl 60/70…considering the fact that i just sleeped something like 8 hrs…how could they have 20+ levels then me.
Where i’m going wrong? There is some exp special system?
