Princess, let me ask you: do you negotiate in GE or battle?
When I first started this game, I used to negotiate, but as I built up my mil-3 GBs I went away from that, and now I never negotiate.
I know that I can defeat almost any enemy, even several ages above me, using proper troops, tactics and boosts.
And I always fight all 3 levels of GE. 48 fights a week in GE gets me lots of PvP Tower points. And pretty much every week I also fight the first half of GE Lvl 4.
And on Continent map, even though I often have all the goods to unlock a province, I always fight instead.
Maybe you already fight GE? Anyway if you don't, you should.
#1. GE is the single best fighting tutorial in the game, as you are always allowed to see what enemy is against you. Deploy your troops to take advantage of A) their weeknesses B) your strengths
#2. Save your goods! Why give them away when you can fight and win those GE prizes?
