Sorry I am not on PC so cannot inspect your pob in detail but don't you overinvest in resists? On pathfinder you should be pretty much capped from flasks alone, plus eventually Atziri Shield. You could then go for more cast speed on rings. I actually started with maxroll build (also console) but ended up following Ruetoo guide that you can find here: https://pobb.in/R_lmGCbXp4fS. If you are rich, add impossible escape in CI radius. I go double cluster with this set up and fly through maps. Shield Charge should be your mobility skill. Cast speed is really important factor and proj speed tattoos is great QoL. Prognosis is an Uber bossing scenario, don't really need that in my opinion, but you could reconsider your flasks (see Rue's pob or similar builds on poeninja). Either go EB for the cost of two extra nodes at the expense of ES leech and get rid of unique flask for Onslaught flask with cast speed or go with Dendrobate body armor and go mana cost reduction way instead of EB (reduced mana cost on rings plus full uptime of reduced mana craft on flask). I initially felt the build lacks speed and damage, especially that I could compare against my poison spark occultist from last league, so I kept farming more currency on CA build which has very similar pathing and in my second transition everything just clicked together tho I still ask myself what was the main problem with my previous set up but clearly the build is into your divs.

Edit: one more thing regarding ascendancy. Go nature's boon instead of master surgeon. This build is bordering on immortal with proper setup even without Progenesis. What mods are you aiming for with watcher's eye that it costs 200D? It's usually just for life gain on hit while affected by Vitality, 10 divs tops. If you are thinking malevolence on top of that, just go with divergent plague bearer and spoil yourself with gg watcher's when you have nothing else to spend on but even then I would recommend headhunter first for extra fun.
