Good call. What's the mega-OP, flavor of the month, faceroll T6 DH build I should build towards?
There's no mega OP T6 faceroll DH build. Her damage isn't an issue... it's her survivability.
There are really only 2 high end builds. Fire Cluster Arrow (the most cookie cutter of cookie cutter DH build) and the Marauder/Zoo build. Marauder Zoo is less burst damage for more survivability and crowd control but Fire Cluster Arrow is full on glass cannon. Marauder build is more viable at T6 than Cluster Arrow but Cluster Arrow build cleans up at anything T5 or lower.
Fire Cluster Arrow build:
Items: Magefist, Cindercoat, Pride's Fall, Fire Amulet, Stone of Jordan and Reaper's Wraps Bracers. You can then use Natalya's set pieces for the rest of the pieces (like the extra Ring, Boots and the weapon). You also get some resource reduction on items like Shoulders. No need for any attack speed in this build.
Skills: Cluster Arrow - Loaded for Bear, Wolf Companion, Preparation - Punishment are the essentials. You can use any fire based Hatred generator (most people use Fire Entangling Shot), Vengeance with Seething rune (for more Hatred generation) and a defensive ability like Smoke Screen or vault.
For Passives Blood Vengeance is a must. People like Ambush and Archery as well. 4th slot varies... if you want more defense get Perfectionist, more Discipline get Nightstalker, more damage at range Steady Aim etc.
For the Marauder/Zoo build:
Items: Marauder 4 pet set bonus plus Garwolf. So you would need Marauder Boots, Pants and Shoulders plus Ring of Royal Granduer and then the Chest piece Garwolf. The Quiver (Bombardiers Rucksack) with the 2 extra Sentries help with this build too. The rest of the items you stack up on Physical damage (Andariels, SOJ) and some CDR. For Gloves you want Tasker and Theo.
Skills: Similar to the previous one in terms of skill. The companion rune doesn't matter as you are getting all of them with this build. For the main skill you use Cluster Arrow - Shooting Star or Maelstrom as they are Physical. You would also use Vengeance - Seething plus a defensive skill. You probably won't need Preparation for this build as much because you have the Bat active so you can sacrifice that skill for Sentries. Reapers Wraps again useful.
Passives: Custom Engineering, Numbing Traps if you want to maximize Sentry damage otherwise you just go with similar passives as CA build.
If you want to go all in with the Sentry build then you need to get the full 6 piece bonus but it isn't worth it IMO.
Cluster Arrow - Fire build is way easier to make and play. Marauder/Zoo build takes a lot of specific items that are rare (as they are class specific set pieces) so most people can't actually make this build. Marauder build is tankier and has more crowd control which makes it more viable for T5/T6.
I personally only need the Marauder Shoulders and the Marauder Pants to complete this Zoo build. I have all the rest of the pieces (I can technically re-roll my Fire SOJ into Physical SOJ).
