Cestus buffs are.
+10% Attack Speed (so about 20 AS)
+1200 Att
100% Critical on next 3 smashes
Vella's only buff is (to my knowledge) a boost in her Cross Counter percentile and allowing her to do it twice while going through enemies.
In short, just because buffs exist and/or have big numbers does not necessarily mean the character is broken and OP and such. Cestus is still bottom 3 for sure.

Isn't that like... All character variations but two?
Pillar Karok, Cestus Karok, Hammer Fiona, Scythe Evie. There's a relatively large gap between Spear/Vella/Kai/Swords and Hammer/Pillar now, so that's really where the biggest damage divide is. Staff Evie sort of gets pushed up with the Top 5 due to the fact she can corona, revive, and has some range: that's literally her only strengths post Ignition. Her damage is easily below Pillar/Hammer, and maybe even Scythe.
Take it as a top half/bottom half. With Staff being in a really weird position of being the only thing remotely close to a support character in this game.
Mostly personal opinion though, but it's based off quite a bit of play and sifting through numbers.
