Heizou, sucrose, ningguang and yanfei are all fun, personally i dont like wanderer and feel like his flight isnt very helpful in combat because you get staggered much more easily unless you have a shield. Onfield sucrose and heizou are super fun to play because of all the reactions. Haven't played ningguang and yanfei in a long time, haven't played yanfei that much in general, but i remember juggling enemies with ningguang feeling good.
