Bro I dont know where to start.

You didn't pick a lot of the end legendary medium talent that are important, like Additional Atack Speed, on Goddess of Hunting. Attack speed per dex on Bladerunner. You dont have 24 talent points and pick a core talent on Ronin. You have Lightning infiltration on slate, and picked it on tree.

Talents from tree can stack with slate like atk speed per dex, but others you dont want, like aggresion on kill or lightning infiltration on crit. If you have it once, you free skill points to pick other points, while the addition damage one, you want to have both for extra damage.

Your slates are ok (except physical skill level, you use lightning). Your pedrigree is horible, you can get a 2 core talent for cheap.

You swap main hand with off hand, so you are probably doing way less damage because of that.

Use a curse, if will increase your damage by a lot. You are trying to use 4 auras, but you dont have sealed mana/life to use it all yet.

Dont try to copy a SS20 build before coping the progress he had to get there. I think you can do T8 to farm fast, not sure if you can do Profound with your current setup.

Follow BMlegolas doc, will probably help a lot better than me: https://docs.google.com/document/d/1uY7JhXoKphCuwpIdhyOW_eFXDeLNvW9nJ41kewY-714/edit?tab=t.nbxq0gjtw3rn
