TL;DR:
Make curse and sleep status known as "super statuses". No armor can resist these statuses expect for UVs that were rolled before this change. Add 1 new statuses to replace them on the 7 status system to keep things fair. 1 status, blind, you can read up here reduces vision area for players and enemies and can cause your hits to miss and deal no damage. The other status, "terror" makes those inflicted more easily flinched and increases flinch time for players and enemies.

I dislike the current status system quite allot. 2 of the 7 don't even happen in the game commonly and are plaguing some armor lines as a defensive stat making it useless in comparison to other armors. So lets push those 2, curse and sleep, away to a new section called "super statuses". This name can change as it is a bid odd. Why push them away? 1, they are rare in both use of players and enemies. Only 7 enemies and 1 weapon cause curse and the only 2 enemies in the game that cause sleep are currently not available to play against in the game with out a glitch or hacking.

What about the current armor lines that either have curse resistance or sleep? Or even curse or sleep status impairments? Well get rid of the resistance or replace it.

Make any armor line that is weak to curse now weak to terror and anything weak to sleep weak to blind. The same goes for those who resist sleep or curse, make them now resist terror and blind. I'll go into a list on the armor changes for these statuses latter on in a list.

What is blind you may ask? Well this thread here and the TL;DR sums it up nicely.
But what is terror? Terror is all about flinching. It makes those conflicted with terror more likely to flinch and also makes the time the flinch animation takes to run through even longer. While terror is conflicted the little sweat bead animation should keep being ran on the enemy as well as a slight shadowy tint on their face.

Armor changes
Give the alimiren crusader set terror and shock resistance instead of curse equal to the status resistance of most defensive armor sets, drop the fire weakness, and also give the crest of almire terror resistance instead of fire. It really doesn't make sense for it to have fire resistance compared to the armor and the past of almire.

Make the Deadshot set, angelic raiment set , valkyrie mail set, heavenly iron set, divine set, and silvermail armor all resist terror instead of curse for the same amount.

Make the Fallen set be weak to terror for the same amount of curse instead of curse.

Make all kat cowls, and the chaos set, weak to terror AND curse for the same amount as curse currently. Curse is rarely seen so it might as well stay as a weakness.

Make the chaos set itself also weak to blindness.

Make the royal jelly, as in purple line not blue, have blind resistance instead of sleep resistance.

Remove the platemail line's weakness to sleep. That is it, no adding blindness weakness or anything.
