What, paying players can't do this? The only difference between the paying playerbase and the non-paying playerbase, if we're going to evaluate them both as a whole, is that one spends and one doesn't. Nothing else about playstyle or...personality? is going to universally apply to only one or the other.
As far as monetization goes, Inno's not doing anything new. They're keeping up with the times, and there's a difference. The game's always been monetized, and depending on who you ask, it's always been 'pay to win' (the most jaded ones, like you, will say 'pay to play' even though that's categorically false). Inno just can't have the same approach to monetization as they did back in the early 2010s because both the game and the players are different now than they were back then. And for the record, no, I don't think GE5 is monetized. I don't really see how that could be argued unless you're also going to argue that something like GBG is monetized as well, since both features can require just as much investment in order to succeed, with the only difference being the military bonuses used.
Anyway, just cleared GE5 for the 4th week in a row. Portraits delayed me getting both the Feathered Serpent and a chain element, but I got a GRF, DSW, and of course the Forgotten Temple! Still haven't negotiated a single encounter. Tested the waters with auto battle this week, and cleared all the way up through 76 with it. The last 4 are probably going to remain manual-only for a while, but we'll see!
Also, SBCs continue to be the most active GB across my guild. Deal is still basically ignored, and after actually checking, I can see that most of my guild actually doesn't have Virgo either. Including myself, there're only 12 of them. All of them were built prior to GE5 and none of them have gotten any levels recently. I suspect most if not all of my guildmates are fighting as far as they can and then negotiating the rest, rather than opting to roll the dice with Virgo for the more challenging encounters. It's nice to have some battles where Virgo can actually be significant, though!
