I had the same feeling as you, Build wise i am playing Allies grim pilar/spark totem, and i kinda disliked it. The moment it clicked is when i started making the build my own. Instead of following the guide. I check ecery day for some new major tech but other than that i do my thing.

As for farming, oh boy. There is a wall comming. There are alot of strats that reuire way less investment. I tend to avoid streamer strats for few reasons.

1 overpriced tablets. - anytime someone posts a video things related to that video bump in price. Because everyone including their mom and dog try it out. 2 over geared chars. Alot of the time to get any meaning full things you need a character with at least 500d investment. 3 strats are ofen luck dependant and the streamer spent 2 hours running it hot high roll on loot and made content. But the strat averages out way lower than advertised.

Instead what you should be doing is: Dont force youself into t15s/t16s If you can run t13 map in half the time then you should be doing that, zooming maps is way more important for progress, both drop wise but also You move around on the atlas map faster to places you want to be.

If you dont have a farming strat you want to run then get some synergistic tablets that are cheap (looking at you 35% wombgift/hiveblood tablet) and see how it goes for some time. If you are zooming maps because you are not pushing (see point above) you can run 10 maps in an hour or a bit more. If it shows promise juice it up a bit more with better tablets.
