What are tactics for a Witch Doctor to use against Invulnerable Minion packs? [closed]

Invulnerable Minion packs have been very challenging for me while soloing Hell.

Generally I've been using Haunt and Poison Darts with Splinters for my single target damage, but Splinters tends to get blocked by the invulnerable minions, making positioning very important.

I'm not looking for specific builds, but rather specific tactics for a variety of builds, so that I can pick one to match whatever build I'm using.

Solution 1:

Make an army, which means dogs, fetish and that big dude, use vision quest, combined with zombie bears, and spirit walk with more duration. While getting an army that wil strike the immune foes you will have 3 cooldown, use zombie wall or grasp of hands to slow the immune foes. The you will get 4 cooldowns. Use spirit walk and attack the boss with full load of bears, you can also do the same but instead of using spirit walk at the bigning, attack the boss untill it unjured, then use spirit walk and countinue attacking. For boosting this Mathod u can use big bad voodo
