Having scrimmed them myself, I can confirm that their aim is very good and definitely not the issue. They are radiants, and their aim reflects accordingly.
The problem that they have is adapting to the meta. For example, when my team scrimmed them (I think about a month ago, when the patch that nerfed astra had been out for about a week and a half) they were still playing an astra and viper on way too many maps. For reference, I had switched my team to Acend's comp on split, bind, for example (look it up). They have kinda adjusted, but they still run comps that are highly questionable in my eyes and that is really the core issue with the team. This can probably be fixed with a little practice tho idk. Their aim however, definitely is good
The fact that you immediately insulted their aim tho is kinda strange, as it seems like you are just trying to demean them cuz they are girls. Unless you are radiant in ur region (send a ss), then I highly doubt u can outaim them. The guy originally was being kind of strange making this a competition, but you definitely don't have to engage, and if u do, at least make your argument correct. Bragging doesn't fix any kind of problems
