I can survive with this, but I will have to stick to 270-300 fights/day and lower attrition everyday, I lost more units currently than I produced to achieve 120 attrition on weaker days and 149 in that "top" day ...
Okay, as the top performer in my Guild this season with 2760 VP (251 VP per day at 11 calendar days)
Even with 1500% attack bonus,
I had to regularly switch to negotiations at 80 attrition. (auto-battles)
I went through an average of
1K of each current good per day. (attr. 81+)
It cost about
200 diamonds per day to play the 4th negotiation attempt on many encounters that were just shy.
It probably
cost a good 250-500 units a day as well. It required a few alternate unit matchups so I did not bring my useful units to critical low.
I could probably tweak efficiency, but this was the raw first opportunity.
I can honestly say: With these changes, There is NO way GBG can be sustainable for continuous seasons for Guilds or Players.
If INNO wants to kill GBG so badly, then just remove it from the game and let the chips fall where they decide.
