I've not bothered more than once with the new domain just to see what's inside, so I've no available full set of either new ones. Diona's kit was built with an old 1.2 guide in mind (which was when I first read it); it could be updated by now but since I'm not farming artifacts I don't really mind. The only one that caused me problems was Rosaria, because I couldn't decide which set (Strayer or Gladiator) to pair with my limited selection of polearms (either Dragonspine or borrowing Xiangling's Crescent Pike); eventually I picked the physical set instead with Dragonspine. I might change since I have Eula now for physical, and have level 80 Dragon's Bane for reverse melt plays.
I cleared Floor 12-3 (4 stars Floor 12) two days ago with my Bennett using his Noblesse set. Team 1 - Hu Tao, Noelle, Sucrose, Bennett. Team 2 - Keqing, Xingqiu, Xiangling, Diona. All level 80/90. Getting the namecard means I'm now actually a bit lazy since I don't need to farm as much for that goal anymore, lol. Still, I did my route again and because I hit cap I upgraded Chongyun's set to +12, which somehow rolled a lot of CDMG. I do agree that it's a lot of time, but since my resin goes into ascension mats, gems, and Hero's Wits I really can't spare the resin for artifacts.
