Itemisation & Gems:
Let me first state that I choose INT on all items wherever possible, however it doesn't really matter if you gain STR or DEX on any items as it will be just as good.
TLDR Gameplay Video at the bottom.
Head: Tiklandian Visage - The secondary stat on this item is essential to this build.
Shoulders: Born's Privilege - Used for the 3-set Bonus (10% Cooldown Reduction).
Neck: Xephirian Amulet - Required to survive against Electrified affix.
Torso: Born's Frozen Soul - Used for the 3-set Bonus (10% Cooldown Reduction).
Wrists: My personal preference is Nemesis Bracers. This is because they are very situational, but can allow you to group an existing elite pack close to a pylon and spawn an additional one on top of it. However Strongarm Bracers & Krelm's Buff Bracers are also a viable choice.
Hands: Tasker & Theo - Use whatever hands you have got with the Stats Critical Hit Chance, Cooldown Reduction, Vitality and INT/DEX/STR, best option would probably be St. Archew's Gage with the stats mentioned.
Waist: Blackthorne's Notched Belt - Used for 4-set Bonus (Immunity to Desecrator, Molten, and Plagued).
Legs: Blackthorne's Jousting Mail - Used for 4-set Bonus (Immunity to Desecrator, Molten, and Plagued).
Feet: Blackthorne's Spurs - Used for 4-set Bonus (Immunity to Desecrator, Molten, and Plagued).
Rings: Ring of Royal Grandeur used to reach the 3 and 4 set bonuses. Rechel's Ring of Larceny provides movement speed for more fluid gameplay.
Weapon: Solanium - Used to spawn Health Globes, and grants Demon Hunter's resources (with Reapers Wraps equipped) which provides a HUGE Damage Buff!!!.
Offhand: Thing of the Deep - Enables you to pickup health globes with minimal movement (minimize the risk of breaking the control you have over Mobs/Elite Packs.
Bane of the Trapped: Provides the Slow debuff to activate Demon Hunter's Cull the Weak passive. Gem of Efficacious toxin: 10% damage buff for your party.
Pain Enhancer: Grants attack speed and may procc additional Health globes (will update once confirmed). Gokok of Swiftness: Grants Attack speed and Cooldown reduction.
Core: Make sure to have Maximum Movement Speed (25%). Put additional Points in Vitality. Offense: Cooldown Reduction > Critical Hit Chance > Attack Speed > Critical Hit Damage. Defense:Life > Armor > Resist All > Life Regeneration. Utility:Life on Hit > Resource Cost Reduction > Gold Find > Area Damage.
Your role as a support revolves around you crowd controlling packs and leading the group to safety, basically like a tank. You should aim to do this by fearing everything in your path using Horrify - Face of Death; whilst gathering all the mobs together into a large group with the help of skill Piranhas - Piranhado. Note that Piranhas - Piranhado also applies a 15% increased damage taken debuff on all affected enemies. Before you begin to engage packs, use Spirit Walk - Jaunt for immunity to all mobs for 3 seconds, and continue to use this ability on cooldown. When everything is gathered, it is preferable to spam Plague of Toads - Rain of Toads to generate as much health globes as possible. This is important because the health globes provide extra resources for your DPS, specifically if your Demon Hunters are equipped with Reaper's Wraps (Bracers). In addition, using Big Bad Voodoo - Slam Dance, provides extra attack speed and 30% damage increase within a 30 yard radius of yourself.
Mass Confusion - Paranoia acts as a secondary fear and also applies a debuff (additional 20% damage taken) on all enemies for an in the area of the spell. However you must be careful using this ability as Affixes including electrified + knockback, fire chain + knockback will bounce mobs outside of the fear range of your ability, and you will loose control over the mobs.
Tribal Rites: Reduces cooldown of Big Bad Voodoo and Mass confusion by 25%.
Creeping Death: Allows your amplifications from your Piranhas - Piranhado last almost forever.
Spirit Vessel: Reduces the cooldown of your Horrify and Spirit Walk, spells by 2 seconds. In addition, the next time you receive fatal damage, you automatically enter the spirit realm for 2 seconds and heal to 15% of your maximum Life. This effect may occur once every 90 seconds.
Grave Injustice: Every time an enemy dies within 20 yards of the Witch Doctor, the latter regains 1% of maximum Life and Mana. and all remaining cooldowns are reduced by 1 second. The radius is extended by items that increase the health and gold pickup range.
3 and 4 Man Settings: In a 3 and 4 man group you should always have an additional tank (preferably a support Crusader). Your role is to control the Elite packs and decide the positioning of your party, whilst letting your other tank gather all the other mobs into your fear range.
