From what I can gather based on my limited skills.

Shielded enemies are a pain in the ass to deal with. New characters like the Melee Lind gain automatic spots in teams because they can break through shields.

CC is apparently in high demand as it now has it's own section in most tier list. I could be wrong but I believe it interacts with shielded enemies in a way.

Most characters that can readily inflicted Stun have moved up tiers. A big example is Chelsea. Her new Arma is on par priority wise with Ferns. However it raises her tier level from 3 To a solid T2/1.5

Antonia also jumps up from T2/3 to T0.5 because of her new Arma allow her to stun much faster than before.

Strangely though Hubble is not on the CC tier list section. She is able to inflict stun with her Ult. That might be too high a price to pay and that's why she might not have made the cut.

Also Nascita isn't on that list. Even though she deals extra damage to shielded enemies. I know I'm missing something in translation and because of my very limited Chinese.

Rumors of a new dodge based function set that would make Dodge teams valid.

Edit: corrected some numbers and added additional details.
