I think Yunli will be better than ratio in the follow up team for some reason:

1) she doesn’t relay in debuff to do damage so her damage will be more consistent m

2) she does blast damage which can be useful for those annoying minions while doing most of the damage to the main boss

3) she’s going to be attacked a lot of times because topaz is a hunt unit and Robin a harmony one and if I don’t miss remember Robin while she’s in ult has lower agro so you just have to put her next to aventurine and she’s going to receive a lot of attacks

4) She does a lot of FUA which translates in Numby having a lot of turns and Robin having more energy

5) and she also has better multipliers while buffed than ratio and she gets a lot of crit damage and energy so she’s going to be buffed all the time
