This is utter nonsense and so are the points made by people defending it. We have people in FE or PE/InA using hovers to clear combat and saying everything is fine. That's not an option for people in the SA like myself. GE80 is about 2000/2000, a full 1900/1900 above my bonuses. Because of scaling and the chance to crit that all SA units have, it's impossible to consistently combat GE5 without tearing down useful city buildings to replace them with garbage. And while useful can generally be subjective, in this case it's pretty clear that losing the ability to get diamonds and FPs in GBG so that I can get garbage buildings in GE is not useful. Yes, hover accounts can clear it through combat, but for the 99% of players who are using age-appropriate units combat isn't an option. Even people willing to waste valuable space on things like DC or VP can't win through combat. VP only kills the first wave, some of the time, and when every single one of their units has a chance to one shot me that's an exercise in futility.
I'm not even going to address the terrible rewards not being worth the cost, or how this is further evidence of Inno milking a dying game for players' last few bucks, or the multiple levels of incompetence that had to mesh together to bolt on this untested and broken idea onto something that was working and now no longer is. Simply, mathematically, there is no way for people in SA to reliably finish GE without devastating their city in every other aspect of the game. The only features in all of FOE in which city statistics matter is GE5, and if you are somehow still getting plundered. Attack boosts matter in GE1-4, the continent map, GBG, GVG, daily quests, plundering, and the PVP tower. It's a bad tradeoff and anyone who thinks otherwise is rationalizing bad behavior
