I’ve only been at it for 3 weeks so I have tried all and IMO the Acolyte guide I’m linking is by far the most beginner friendly build I’ve played: Fastest Guide for First/Solo Character Leveling
I’m of 2 minds about stumbling around with all classes and figuring builds and synergies out on my own. Yes, that is fun and very rewarding, but it can also be a lengthy and painful process full of mistakes that are not easily corrected.
The passives are easy enough to re-spec for cheap amounts of gold but re-speccing skills even by removing 1 node or ditching a skill and speccing a different one is very punishing at the early levels when you’re new. It’s easy enough to do that when you’re high level and skill XP is gained easily but not at all in the early game up to and including the end of the campaign.
I have no problem following a well explained guide and getting up to speed that way when I’m new at an ARPG, all of which have their unique ways of building characters.
In this game with the punishing skill re-spec system at low levels I honestly would recommend playing first by following a good guide and only after doing that for a while, use what you learned to try out your own builds.
Just my 2 cents as a fellow recent noob myself
