Assuming the old ZEMs on the wiki were close. The new best ZEMs in the Game:
Permafrost Caverns
Kedge Keep
Runnyeye Citadel
The Hole
Infected Paw
Lost Temple of Cazic-Thule
Gorge of King Xorbb
Estate of Unrest
I take it with a grain of salt about the Cities of Kaladim, Oggok, and Felwithe getting a 33% bump from 100 to 133, I think it actually went from 75 to 100 and the wiki values were wrong before. Oggok felt like it had a huge xp buff already. I think alot of the city values on the wiki were incorrect before. Makes more sense that all cities would be adjusted to be the same ZEM.
