I can’t recommend you any builds, but buillds are really not that needed in LE, since you can easily adapt a build.
If you like DoT Type abilities i can really recommend to check out Spirit Plague(Acolyte Base Skill), i think it’s one of the most interesting skills in LE, it has so many different applications.
By default it’s a (almost) single target DoT (you can hit multiple enemies if they are very close and the DoT will jump to a nearby enemy, if the target dies).
You can change the functionality, so you can manually spread the skill on top of the spreading on death, you can make it spread to multiple enemies, you can make it spread if you hit the target, you can make it spread if you crit a afflicted target.
You can combine this with some other DoT type skill or go a hybrid hit/dot build.
Skills you can combine with it very greatly are Bone Curse, Harvest, Rip Blood for example.
Depending if you wanna go caster or melee.
Just go for it, experiment. See what you like. Generally each and every skill is endgame viable if you put enough thought into the build and synergies.
