I concur. Before the current GBG season I was able to autobattle to 80 attrition before taking significant damage to my (1) hover tank (7) rogue army. I'm in PME. Depending on the number of guildmates on the field during a swap I get in between 225 and 275 battles each swap. This current season I'm not able to get past 60 attrition on auto. Nothing has changed except I added 96 attack and 32 defense when the Fall Event ended. More attack, more defense, less ability to fight without taking damage. I get it that terrain plays a role but I don't think it's likely to get "bad" terrain more often now, than before, unless something changed. I don't pay attention to the troops that I'm fighting because I'm using hovers.
