5th defensive slot vs upgrading fortress

Don't worry, it does. Well, I myself got the 5th OFFENSIVE slot and balanced it with lvl 2 defensive fortress.

My thought process was that I was more scared of the possibility of fighting 5 defense units with 4 offensive units of my own than the opposite. It will also make attacking significantly easier whenever I'm the one with the numbers, obviously.

However, I didn't want to neglect my defense either, and probably more than one attacker won't expect to not have extra stats.

I was originally thinking to get the fifth member, but I don't think anyone can afford both this and both bonus structures for next week, which means if you go immediately up to 5 members, next week you'll be down a level in one fortress or the other for at least a few days.
