It seems to me that a GB that would convert both attack swords and shields into city defense swords and shields, this is the solution that would simultaneously reduce the problems with the set of blue stats, and on the other hand, this would not require the global destruction of red stats in the city only for GE5!
GB can be made more accessible or less available by varying the era! In a low era, it will be cheap both in terms of goods and pumping, and in Jupiter it will be more difficult!
It is important that such a GB has 2 multipliers! 1 is the level, 2 is the player's era!
For example, give 1x for Jupiter, 0.9x for Venus, etc.
And for levels, 1% per level, after 10 1% for 3 levels! As a result, at level 100, your GB will convert your 2000/1500 into 800/600 bonus
At the same time, this will not eliminate the need to hunt buildings with blue stats, but will give more players an entrance ticket to GE5, as well as more chances with the help of hands, and not auto attacks, to climb higher in the progress of GE5
