Combat is very "meh" imho, and since they revamped it and removed the "cheese tactics" (basically perma-stun on most non-boss enemies, combined with how hard bleeds hit) I consider it mostly a nuisance as it really pushes you to just be the cheerleader of your Thralls (which are *much* stronger than you, so letting them do the work make sense, it's just not very engaging. Though I think they were messing with remediating this. Somewhat, anyway). The exploration, world building and well, building aspects are great though.
One thing of note is that due to how long things take it might be worth considering running your own server (if you have a PC somewhere that is on 24/7). If you combine that with some tuning of stuff for a more single-player experience (wish there was a way to decrease requirements of only "common" resources though, and leaving the "rare" alone, but I digress) it takes a lot of the slog out of it since you can just queue a bunch of work and let it process overnight.
It has a few other advantages, or rather, it does away with some major disadvantages of single-player too, namely that everything despawns once you go too far from an area. This can, of course, be (ab)used to get the spawns you want, on the other hand it also means that if there's multiple desirable thralls in a location you can't really grab all of them since the rest will despawn while you drag the first to camp (even if you knock them all out). If you run a local server otoh, it really does work like a "real" server with all the perks as well (like stuff being actually persistent, at least until you restart the server)
Of course, the major drawback is that the server software is a technical disaster and leaks memory like a sieve, so you kinda have to restart the thing at least once a week anyway.
As for things I usually tune (off the top off my head):
thrall breaking speed (think it's usually set at 0.25 of normal)
resource requirements (0.5 or 0.25)
how quickly the purge bar fills (if you want purges at all, if not, well, you can just turn them off. Worth noting the best Thralls can only be acquired from purges, and yes, they are better than normal "named" thralls)
how often you need to drink (food isn't as much of a nuisance, the defaults for water otoh...)
Of note, all the numbers in the server tuning window are multipliers, so 1.00 is 100%, so if you want to speed things up you don't make it 2.00, you make it 0.5 to double the speed.
