Build advice Cyclone Berserker

I am trying to follow the Odealo Cyclone Berserker build here https://odealo.com/articles/cyclone-berserker-marauder-build

IGN: cheesecakenl
Pastebin build: https://pastebin.com/xyT9LuQH

Currently running yellow tier maps and often die on Legion and breach content. According to the guide I should be able to run T16 content with a lvl 84 char.

Am lvl 86. Missing the main 6L Starforge and last 2 Ascendancy points from Uber lab.

Looks to be a leech build but while playing feels like I am missing defensive stats.

HP: 6122
Shield: 0
Armour: 2873
Phys. dmg. reduction: 19%
Resists: 76%, 75%, 75% and -11%
Move speed: 38%

Advice, tips and improvements for my current build would be much appreciated.

May i ask why you dont ask this in the Builds Thread then?
or atleast link the build?

Your Armour is too low pretty sure thats pretty much it... make use of your flasks... get a granit flask instead of double life
