{Standard}Looking for suggestions and opinions to improve my build (Cyclone).

yes, it's one of those post, i'm sorry.

So to avoid making it unbearably long, my build sucks, i currently main in std a lvl 89 FB duelist.

i have a pair of legacy FB (974%) that i dropped a long time ago, it's basically the "fanciest" item i own, and thus i felt it would be the best build i could invest in to get into high level mapping, i can't exactly say i regret it cause so far it's been "fun" but it's very clear how inconsistent it is.

so the issue is if i don't know if i just fucked up my char and should wait for the reset after leagues end or if it's just a better way for me to go around the cyclone.

my stats( Great old one, FB, Carcass jack, abyssus,meginord rest rares):

5l cyclone: 28k tooltip dps ( i have no idea how that AS bug works but this number goes up to numbers like 200k depending on flasks and buffs, this is just my default number with HoA and hatred on, links are CyC>BM>FA>fortify>Inc AoE).

of course, i switch to conc effect depending on content, for shit farming is use AoE, the dps goes to 44k with this switch.

4.5k hp 1286 armor 2.5k eva 44% block 10% spellblock capped resist, no chaos resist.

so the issue is really the Survivability, i can't help but feel hard-gated due to this on higher lvl mapping, so many combination of mods make it so much harder than it seems it should be, but that feel like it's a consequense of the build.

the question: should i continue to invest and refine the build until i get to a more optimal point, or is there a more efficient "out" to it? i've seen many interesting disfavour builds, i assume i can sell or trade my gloves for one and have a better time doing it, what do you guys think?
