We realized as much here:
Exploration Failure and Spread will prevent this.
As for nerfs not working, buffs and nerfs are 2 sides of the same coin. A nerf for some empires is a relative buff for others, and vice versa. Just because people dislike being nerfed doesn’t mean that it is a bad feature. People also don’t like losing attacks.
These are also planned, but no ETA on them yet.
I’ve split your idea to the https://discourse.imperialconflict.com/t/galactic-event-temporary-buff/6107/2?u=i_like_pie thread so we can discuss and vote on it further there. ![]()
