That's brilliant! I just hit level 20 before the server went down.
But to be honest, I hope they make this change permanent. I think Level 52 is too harsh for casual players. Level 20 is a much more realistic goal.
I'm a gatherer at heart, and for the past few hours, it's been killing me not being able to gather all the plants I see. I felt the game was on hold, urging me to level as fast as I could.
But now that I've reached level 20 and I can finally use labor, I feel like I can finally start to play properly. It's a huge relief.
