Remove connectivity. There seems to be some strange interaction between Overload and Connectivity. Overload encourages us to not have too many defended and attacked pieces, as this may expose us to various tactics. This feels somewhat like it is in conflict with Connectivity, where pieces are defended preemptively. Here I take the "pick one or the other" approach and just remove connectivity, while strengthening the effect of Overload to compensate. The reasoning is that if we defend our pieces preemptively, then it does get attacked, we want to do something about it so we don't get penalized by Overload. On the other hand, if it doesn't get attacked, then there's no need to defend it.
