Sarcastic possible future for GbG:
January
The name Guild battle grounds will be changed. As it's noticed that the name has become inaccurate. As learned from the feedback. This is why Guild battle Grounds will be renamed to: Guild battle Farms. To make it less confusing for weaker guilds and new players.
Also the improvement has been dropped. In favour of a better solution, that will be introduced and tested later in the year.
February's 1st GbF season:
Introduction of Forge creditcard. You can charge this with real cash, the credit is shared by all you're accounts worlds. It can be used to purchases more easily FoE+, event passes, 1 month add free package but most importantly instant complete GbF buildings for €0,50.
This will start with AB live test, cause at the Beta the feature can't be properly tested.
February's 2nd GbF season
The option to purchase instant GbF buildings is preferred by players, according to the AB test. So, the Forge creditcard is now available for everyone. Also, GbF buildings instant completion will cost €0,50 instead of diamonds. Like the Halloween AB cash event pass test, only 1 test round is needed.
All of the above is just pure sarcasm but wouldn't be surprised to see this would be introduced, instead of this improvement. All sarcasm aside, this improvement is clearly doing what it has intended to do. It doesn't take a genius to understand this. Judging from the echochamber this topic has become.
Better solutions could've been done, more subtle, like limiting the maximum number of GbF buildings and thus the maximum support. Besides of each SC giving an individual X% chance to not increase attrition. This would easily making it impossible to fight infinitely. I wouldn't be much surprised either if Inno has listed all suggested solutions and tested them on the Alfa server and decided to roll with this solution. Which seems to work as intended, seeing how this discussion has gone.
