You guys know you're ranking them based off level 1 SA right? They still got room to grow.
Still interesting discussion, but I think seeing them maxed will change some opinions
That being said, does anyone have the maxed SAs?
I don't know all the level 3 SAs except Hack N Splash caps at 15 seconds and 3% damage per debuff removed. If I remember right, Purrfect Dark caps at 10 Seconds for debuffs (timerless) and 50% HP to instakill (still 10% chance and head hits only) and I think Feline Lucky caps at 25 second buffs (chance stays the same) and 3 precisions per 7 seconds.
Dark is going to be an incredible counter character with a bit of cheese potential (10 seconds isn't too long), and if Claw & Order lowers her damage % for activation to 5% like I suspect she'll be incredibly strong as well.
If Kitten raises her debuff conversion to 100% and raises evade chance to 15% she'll be an amazing bronze defense, but it'll probably be just 50% convert and more haste, so still fun but not mind blowing. I don't think she has any unusable variants. At worst she's like Eliza, every variant has use even though some are gonna be much better than others.
