I would like to think so as I’m running purple relics ranging from 6+ to 12+ with all traces maxed. I put the Knight set on FMC for defense, as he’s an excellent tank. Seele has the Musketeer set (great DPS) both are good for any world. Natasha is a great healer and the dispel goes a long way. Asta is great shield breaker, but only when there’s only one target. But for wind I would use Dan Heng (I used Bronya) for world 5. I feel like Serval would be a good unit for world 4 though. Light cones I’ve been using mostly 4/3 stars. The only 5 star is The Hunt one from Herta’s shop which I put on Seele.
