I'm hitting a sort of "Oops, am I getting too ambitious?" moment with the resists :P With how much it changes balance, and even messes with several bard skills (e.g., song of living nightmares is now meh except against armorless enemies), I have to go all in. So I definitely want to get the formula right. I've made it so int and strength boost status application chance by 1% for magic/physical statuses respectively. Constitution now boosts resist by 1.5%.
Resist Chance = Con(1.5) + Perseverance(3) + Armor Percentage - Strength or Int(1)
I'm also considering whether a critical hit should boost application chances, maybe as a factor of wits. Say, critting while using Sawtooth Blade when you have 20 wits would increase application chance of bleeding by 20%. This would also make savage sortliege slightly better.
I dunno though, I don't want to over complicate it either.
