Give up now if not level 55
A recent change to the combat (raid) pairing system means that level 55s(max level) get to slap you silly and take your points and you can do nothing about it since there is no way a non fully upgraded army can beat them - you cant even make the units until you hit level 50.
How to compete - give them lots of real dollars. This takes freemium to a whole new level.
Basically this change is the beginning of the end for Zenia since nobody wants to be unfairly stomped on continuously.
