I haven't seen a lot of calcs / guides regarding post-novaflare Firefly, but it seems that her 4th teammate slot (assuming sustainless) is quite flexible now and Bronya / E1 Tribbie / RMC are all viable apart from the usual RM / HMC.
My question is - is there an "undisputed" best fourth slot for FF teams now, or is it purely situational? What are the speed tunings for each of the options?
Also for RM, I assume that the build now is to reach 120 speed (or whatever speed that, when paired with Vonwacq, let's her act before FF's first action), then you want as little speed and BE% as possible so her ult uptime is better and enemies recover faster to be broken again, but would like to know if that's not the case.
I currently have E2S1 FF, E2S1 Dahlia and E2S1 Fugue (Cipher sig)
