I've been clearing a whole lot of content and never have to care about FuA/resolves. Even with the addition of FuA, I still hate resolves since I suck at making heart columns fast enough, especially on 7x6 boards. I just used my 3P Arena team to blindly go into Bigfoot (just cleared that dungeon once before when it came out, didn't remember much). It's not a very difficult dungeon, but those saying the 6x damage is not enough, well I do not agree. This team barely has any killers as most of my useful killers are reserved for the DMeta team and I haven't farmed A3 in a while. Gronia hitting for 188m with Vraska board! You go girl!
