you shouldn’t really worry about uptodate on most of the levelling builds, they still work fine even if they are several patches old/so far back as 1.1.5
i think tqFan is on hiatus, so the latest round of levelling builds from ex Sudoku isn’t on yet Profile - HonorabruSudoku - Crate Entertainment Forum
or Ralf Profile - S.E.P_Ralf - Crate Entertainment Forum
then for endgame it’s a bit more messy, but, assuming GT scraped forum builds correct/forum builds were proper formatted to be scraped you can use either GT builds, plop in the desired skill or item you might want or feels carry over from levelling Grim Dawn Builds - GT builds also list by patch nr
other than that you have to either search the forum manually or go with ex top20 
Personal recommendations, depends what you like, spam caster or CD caster
I’m still a sucker for AAR/lazor beam’ing, Stun jacks is also good fun, love Aegis of Menhir (spam only avail for endgame), and BWC
for CD casters you have Runes, BWC, Doom bolt(pseudo spam), Storm Totems
The easiest of these, (not necessarily most fun), that also connects or overlaps, is Light’s Defender Elementalist totems+stun jacks, can level as totems with CD jacks and it’s super easy/strong, and goes into endgame nicely comfory too even if then switching to spam jacks
there is lots of fun stuff out there, so i’d recommend looking at the different cast skills, see which you like/might want, then look up builds for that specifically, there should be builds posted for everything.
You might not enjoy AAR as much as i do and might want FoI instead, you might not think Totems are as cool or want Mortars or Sigils instead, likewise etc etc etc BWC/Ravenous Earth so forth
