Was considering getting E0->E2 Firefly instead of a new character, but after trying her out in 3.4 beta, it's clear that her time is over. I tried her out at E2 with the same gear and team that I have on official with 3.4 MoC, but it took her 9 cycles for Svarog side. Saber E0S1/Sunday E0S1 Bronya LC/Tribbie E0S1 DDD/Gallagher did this in 4 cycles with ease, with mid substat rolls.
