Please consider for Black Friday, allow allies to be dropped for full value and buildings at reduced prices.
This would benefit all, but could help ease the gh conversion. Considering that you has your hand out for money then lambasted the gh immediately after taking their money, it seems like you should be considering something to help the number of players you've just alienated with a bad sequence of events and no chance to react.
You should also consider the fact that many based their decision to go gh on kaw_admin's very own feedback that the match up systems was working so deal with it. We did. The best was, in your system, was to have a mix of builds that included gh and fewer mids. That forced mids to a stay mid/no war choice or go gh and war.
