Just keep in mind, before asking for nerfs, gear is good, hundreds of crystals into rerolling farsight globe jewels, bunch of xis runes, includig wasting 2 on chest (first roll was trash). It isn't super extreme gear as natasha or umo projects (used only 2 endless light that just dropped on the way). Regardless this char takes a lot of grind to gear this way.
Used mostly overkill to avoid doing another ancient's hand version. 110% WDM really has potential

Showcase of barb using tri-elemental damage from nephalem spirit uberskill (in melee version also kraken stance).
Keep in mind for this to be that effectieve high elemental pierce is needed which means hard to get/expensive gear, few xis runewords, lot of decently rolled farsight globe jewels, and preferably endless light umo. Total pierce was ~160-170 fire/cold/lightning

As you can see only 2 endless lights on empyrean band. None of farsight globes was -2/-2/-2, (so 6 to relevant elements), most of them are between 4 and 5 total pierce.
It is important to prebuff your nephalem spirit (and shamanic trance for mana regen) with +skill switch, adds a lot of damage.

Overkill is interesting alternative to melee skills, works vs bosses that counter melee builds. Allows for consistent kills.
There is no Zorun Tzin video, as I previously made dedicated video about him, fight looks pretty much the same. Melee works better than overkill vs him (small body = less hits), fight is random, you can get lucky streak of hits and kill him in 15 seconds, or it can take few minutes if he decides to spawn lot of totems. Kills presented in video can be quite consistent, with some rng in baal fight if he spawns act bosses. Astrogha can be killed that fast that pretty much 10/10 attempts, where with melee there is high chance of dying. By standing away from it, you elimate risk of accidental totem kil (because totems are spawned at your location).
You can also observe massive slow on kabraxis (screaming eagle +50% slows target), this sort of slow lockdown can be recreated in every attempt, deathless trophy farming is possible.
