I've been playing pretty steadily and will continue to do so. Gotta get those Abyss Legendary Hero Battles, they're probably the most fun I've had with a game all year, but I know they're not to everyone's taste.
Spent almost 300 stones on the Legendary Azura banner just now since I really want infinite copies of all of the blue units, got an Azura early on, then nothing for well over 200 stones. I'm at a 13% rate now, almost 13.5%. And you just know that when it breaks there won't be any blues on the wheel...
Re: "the way the game is going", this is going to be a controversial opinion, but I think Surtr could have been good for the game. He ultimately isn't, but he could have been. Enemy phase teams are fundamentally less interesting than player phase teams and were overwhelmingly more powerful, so a harsh counter to them to force the meta to decentralize should have been a good idea. Unfortunately Surtr is minmaxed in such a way that he's just an even more powerful enemy phase unit who also happens to be good against old enemy phase units. I think people are vastly overblowing how hard he is to counter, especially in arena where you have unlimited time to kill him, but he is definitely a huge missed opportunity and a bad design and that sucks.
