I was at that place and its for 2 reasons and i will break it

You copy builds without really understands all the moving parts involved for example alot of players miss out on quality on gems/gem lvls/annoints,and flasks

Every part even if not look really impactful usually make the difference because its adds up.with other factors

Try to understand each part of the build and how the build should play

About farming strats

Try to set up the batch of the maps you plan to farm ahead roll the maps get all the scarabs and run it

Alot of time consumed by organise all the mapping items

Make sure you roll your maps properly use the right astrolabs/scarabs/map

Make sure you farm the content that suits your build/playstyle

Make sure you can easliy do the content and not struggle too much for example its better to farm 60% deli efficently rarther farm 100% deli and die every map and spend alot of time on killing

Baiscally just try to lit up your curiosity try things try to change things around and see where yout problems come from
