sirblu Inno generally doesnt post oficially the maths behind mechanisms, but fandom wiki does, so better check this out.
Guild Battlegrounds is a feature which was introduced to the game by InnoGames on 14th November 2019. It is envisioned as an alternative guild feature to Guild vs Guild. It is also an attempt of bridging the gap between mobile and desktop players. However, it is not a replacement of Guild vs...

As for the new atrition changes
I thought in the begining that fighters will like the changes and negotiators wont. Truth is almost noone like the changes in the atrition.
I understand that the infinite 1750 of 100+ atrition was something that needed change, but as many mentioned above, the curve doesnt seem fair. Having double attack-defence boost in just 5-6 battles is not a nice adition.
I dont have a problem with negotiations become a bit more demanding earlier, but still the whole atrition system needs a new balance.
My proposal is this.
We keep everything as it is till atrition 20. After atrition 20 and till 40 or 50 attack defence boosts go +5 for every atrition, then for another 10 atrition att-def boost goes +10 , next 20 atrition goes +20, next 20 atrition goes +30 or something similar. To have +40 or more boost just for 1 atrition is a joke and its actually punishing players with 1000+ boost. We do need a wall somewhere, but not so early in fighting mode.
Negotiations also need a wall . How ? After atrition 50 or 60 , make it +1 good for every atrition, so if you have atrition 100 you have negotiations x50 or x60.
The wall in negotiations should be more or less near the half atrition of the wall fighters have.
the "wall" in negotiations doesnt exist, someone could have thousands of goods and still being able to drop serious amounts on GBG, but after 1-2 months the goods per day is what will matter.
And yes, Siege camps need a rebalance too, maybe have less impact or make them more expensive. Less impact would be more balanced though, cause treasury goods are almost infinte for some guilds.
