I've never bothered with the war business but do belong to a team.
I am at 470 storage now and easily maintain a nice balance.
We all should remember how this game and we started, slogging along building as best and fast as we could.
Now we get another chance or three to create our regions.
Just another slog and as of now, nothing more.
So, just enjoy what you can make and enjoy what we comes our way.
It seems as if the issue of needing items from regions you are not part of has been fixed which is great and with three sections open and building and almost 50K population, this is mellow fun.
