I'll start by saying that the changes i am about to suggest, are not meant for an increase in dps, since Cestus is already a good enough weapon as is. they are purely meant for making Cestus a healthier and more fun weapon. I'll first explain my thought proccess for the changes i'll suggest. if you dont wanna read that, skip to the "Changes" part
Cestus is currently the only weapon that has two passives that basically have a low chance to increase his attacks damage (Pillar's bone fracture doesnt count), which means two passives that are completely RNG, and out of the players control, while having the ability to make a noticable difference in his dps outcome, mostly in normal raids, in which afew extra procs make up a bigger part of his overall damage.. Cestus also struggles alot from a problem that Spear Lann had, and they kiiinda "fixed". that being that it struggles when your attack speed goes up, because the faster you are, the less absorb frames everything has. Similarly to how spear lann's dodge is, and what they did to help him with that is give him iframes on his first glide, which makes it possible to dodge-glide for more iframes..
after that, there is a bug in one of Cestus's three passive buffs, in particular his Destroyer buff, aka blue buff, aka permanent critical buff. which pretty much makes it so that some times, instead of going back to four stacks after resetting it, it goes back to three stacs, messing up the players flow completely.
and "lastly" his hurricane active needs some changes, its currently not at all safe when you try to connect hurricanes back to back, as it leaves you wide open to bosses, and there is no way to even cancel out of it, meaning that sometimes even if you use it correctly, you are bound to get hit.
So now i'll give a few ideas on how to fix those main issues.


. I like the idea of being able to use it alla pillar counter, though without cooldown. Just to keep the theme of the character alive
