I suggest to boycott level 5 in guilds. Just don't open it. We looked once, made sure that it was trash, and we don't go there anymore. Just this will help to correct the situation.
Or don't whine, but just put up with it and rebuild cities.
First I going to "try hard" if I can re-build my city here on beta to see if it's "even possible" to get it working and if it turns out not, then I don't know what to do, but probably I stop beta testing. IF it works, then I go on...
I give it 2 years, because it will take a lot of time to:
1) gather enough buildings that provide boost for defending army, especially attack boost is hard to get.
2) I don't wish to simply delete (sell) valuable buildings I worked for to get them, so I have to gather a LOT of "Store Building" items !! This will need a lot of time too ! (I just maked a start with the re-build and my Store Building items are already all used! )
In the meanwhile I do not open GE5 till I know for sure I can at least win the first 4 battles (read : first upping my boost!!) ...
If Inno means with "a marathon and not a sprint" the above description about "re-build cities over (long) time" , then they're right ... !
