I finally got the medium badge... beware it took me a bit more then 3 weeks and had no fun.
I also had a problem/bug, which i suspect was intentionally: by logging every day you can get rewards, but once in a few days this seemed to reset for me (ensuring I could never get more then the 3-4th daily reward instead of the full week... which wouldve let me buy a permanent profit booster... and might have made this lvl3 city agony slightly faster)
Awesome game :3
But... i think it would be a little bit more awesome, if we could choose which class get which equipment (like focusing our mages on range but still having the tanks walk around with heavy melee equipment)
