What are the next steps for my build? Struggling to improve

My current build is a PF MF CA of poison as follow: https://pobb.in/qnatVvClkU9e

I am currently doing T11 fully juiced (+2 proj corrupted, 4 sextants, 4 scarabs) and I find it long to kill some mobs/packs and while i facetank most spires, I still occasionally die to random stuff (never clear what kills me). I can do 5 maps deathless (but slow) and one map using 4-5 portals due to random unexplained deaths.

I am looking for:

1. how to improve my build (both more dps / more tankiness) and a path to take it up to T14+ and click all quantity altars without looking too much at the downsides
2. how to configure PoB to understand my "true" dps for mapping. I think I configured mine optimistically, and my dps still looks like shit. I thought these builds easily hit dot cap

I have tried looking as some streamers, but their builds are either not too detailed or not MF based. I did look on poeninja too and can't see the major differences, or at least the upgrade pathway with items of less than 10-20 div initially, and long term 80 div items

As I see it:

• I can get+20% to +30% dps with a 80 div bow which I don't currently have. I think an intermediate one is not worth it
• On my tree I am overshooting on poison chance by 15%, but can't see where I could save a point on the tree. Although it might mean I can afford to find a bow with less poison chance (I really don't want to have HoAg as I perceive as a massive waste of reservation)
• I can improve gloves a bit (under 10 div), probably on getting more chaos res on them and get near 75%. Or more towards dps, but I think ehp is the safest bet here. Implicit could be better, but we are talking a few % and a lot of currency to hit them, so to be done when/if I am swimming in currencies
• I can get a better life flask, will give a bit more regen, though will mean more frequent usage. Any recommended mods on it? I just went with my best guess here for my needs as I don't have CB immunity elsewhere
• I need 5 more points to get from 45% suppression to 99%, but I only have 4 points left on tree and don't know where to save one
• I am a bit tight on mana, could use an enl 3 or 4, but that means I need to drop a gem somewhere. Not sure if I could drop the cluster with enl 4
• Pob tells me divine judgment is a better amulet anoint, and most people take Deadly draw which is worse according to PoB, so not sure. Keeping mine for now for the poison % and the fact it's the 2nd/3rd best choice
• I think either poison or bleed is causing me issues and may be a reason why I die. I sometimes see my life dropping to a dot post fight and don't know what it could be
• Not sure about pantheon. Probably need to keep the stun one, and maybe the dot one?
• I could get a brewery belt, but I'd rather prioritise having 2 adjacent flasks to my tincture to guarantee uptime (I am dead if my flasks drop)
• i should put item rarity support on my 4 links, but am worried about the dps drop
• my quiver looks ok?
• Is + arrow useful on this build or a waste?
