I was in that thread. She was being incredibly combative (any form of criticism, even constructive, was met with really shitty comments from her while assuming everyone was white and her comments reflected as such) and she was also espousing black nationalist and black supremacist propaganda which made even redditors cringe.
Mods were deleting comments from users to remove her replies, it was bad.
I’m going through some of the racist comments against her and the users who used the no-no language are regulars in r/genzedong and r/sino.
Catalyst users need a lot of Elemental Mastery, usually about 150 as it has diminishing returns.
EM is required for reactions to deal more damage.
Mona needs Widsith (bis).
Barbara needs Prototype Amber (bis).
Lisa needs ATK% (Skyward Atlas, bis) or Energy Recharge (Favonius Codex, bis) weapons. (unfortunately Lisa needs to be C2 to be usable as she is incredibly frail, but her cons are found on Standard Banner and they are rarer than 5*s)
Sucrose needs Elemental Mastery weapons (Sacrificial Fragments [bis] or Mappa Mare) and she needs about 400 EM for her best build.
Mona is a support and subdps. All she does is taunt and boost damage with her burst.
Barbara is a healer. Healing and wet status applier, not much else.
Lisa is a glass cannon, but needs a lot of setup. High risk, medium reward.
Sucrose needs as much EM as she can get due to her buffing other character's EM. Sucrose is a godly support who is necessary for the meme damage team.
Lisa is garbage, skip her.
Mona is great but she's all over the place unless you play her as support.
Barbara heals and applies wet, pretty much it. She is meta but she lacks in the damage department.
Sucrose is fantastic but she's squishy as hell. C1 is required for maximum efficiency.
Meme Damage Team:
Bennet C1 + Mona + Sucrose + ??? = min six figures if built right.
