Old gladiator impale

Hi,
Just wanted to come back to PoE but I have problem with respecing or changing anything in mine build/items just get to good levels with mine character.

Is anybody possible to check mine character Darkux and what would be possible to do with those items?? I have no idea what meta is now and how, and what could I change to get soem results like t16 maps runs.

I would respec to slayer and and use it as flicker strike slayer or frost blades slayer. Then there is also splitting steel builds with vengeance cascade.
For example there is few league old frost blades slayer in my profile with similar gear. Find youtube 3.19-3.21 guide and follow that.
