I'm happy with the roster I've built so far, but from here on I'd like to build team synergies. The problem is when it comes to the current/upcoming premium comps like DoT, FUA, and Break Effect teams, it feels like I'm already too far behind and/or the timing is bad.
DoT - I don't have Kafka, Black Swan, Ruan Mei, or Huohuo. This seems like such a fun team, but there's no way I'm saving for all those reruns.
FUA - I have Ratio, Aventurine, and Clara, but don't have (and won't pull) Topaz or Robin, and Jade is a big maybe.
BE - I don't have Ruan Mei and won't pull Boothill or Firefly. I bet this comp will be very meta in the coming months, but the timing is impossible for me since I just blew all my jades on the 2.1 banners.
Basically, a future FUA team seems possible for me (especially as more IPC units release), but I just have to concede that the DoT and BE teams ain't happening for me.
The wisest path I can think of is to save up for 2.4 and wait for premium teammates for Acheron, and see what the next powerhouse team comp will be.
