Io is still very strong, as she still has the capability to 5 zone even with her nerfs
s-
Corvus was already strong before his buff, Strix and Kinessa are still insta-bans on good sniper maps. BK is still great. Inara is the strongest point tank. Andro was not nerfed and still is a strong flank.
a+
Ying, Grover, Jenos, and Furia are great support picks. Ash and Atlas will probably be the best off tanks. Term is great in small maps. Vivian shield was not nerfed so she is still good and Sha Lin is hard to play but has a ton of utility. Maeve and Evie have amazing mobility.

Damba is a good pick for a team that lacks cc. Grohk might actually be viable after his healing buffs. Barik is O.K, he is mostly only picked if Inara is taken and your playing in a bad Terminus map (E.G. Fish Market). Raum and Drogoz are good, but have a lot of counters. Ruckus is a good dive tank. Lian, Cassie, and Tiberius provide good damage. Viktor and Buck's sustain was nerfed, but they are still good. Zhin is good as always. Lex Retribution buffs helped him a lot. Talus is still good.
a-
Pip's Combat Medic buff helped him, but his heals are still lackluster. Fernando Shield buffs might make him an O.K. shield bot. Khan nerfs + resilience buffs were bad for him. Makoa buffs are good, but he is still pretty bad. Tyra, Willo, and Dredge have area denial, but not much else. Moji changes are meh.
b
Pretty bad champs. Koga has good mobility, but his sustain was heavily nerfed. Imani is good against flanks, but she isn't really that good. Her ultimate is easily countered. Seris is still a heal bot. A 10% increase in healing is not much.
c
Torvald and Skye are easily countered. Don't pick them.
