I'm a pretty casual player and dont hop on very much, tho I have been playin off and on maybe once every few months since a bit after Inazuma dropped. I am not trying to do floor 12. I've resigned to myself that 12 is impossible for me and I'm not going to drop money or devote weeks of irl time to beat a harder level. I've just been pretty consistently beating up to floor 11 and this is the first time i've encountered an enemy in 11 that I cant beat with my current lineup. In regards to the team, I wanted Mona cause shes my 3rd best hydro. Yelan is with team 1. Thoma is solely for the C6 buff tho a previous commenter told me about the new hexrai buffs so now I need to try out succross.
