Agree with all the statements above. Used the "attrition" word to get related with GBG boost multiplier values changing while doing fight and negotiations in the GBG.
Each encounter has different boost values if we do battles or negotiations. Under level 1 GE, after finishing 3rd chest, boost values gets increased and after completing 4th chest the boost values get decreased and again same kind of incremental and decremental change can be seen moving further in GE.
Myself asking like, button/icon to give user an option to see the boost values either fight or negotiations before entering into 4th/5th or any chest to see what was the challenging boost values for next available encounter. In GBG, goods multiplier also shown by clicking the attrition button in a small screen.
Adding a attachment, learned just now how to take the pic from the game. From the image, last two row item boxes saying attack penalty and negotiation multiplier, myself looking to get the same for the GE. It doesn't need to incremental like GBG with attrition number, for GE if that icon/button comes up displaying the attack penalty and goods multiplier is enough. Does not looking for the attrition number.
Also sorry, if my english gives much trouble on understanding.
