Just to share build, I'm currently using:
azmodan runs with 5nv stack:
And compilation of elite kills with exact same build:
Video speed is x3.
Build without revenge, burst damage vs elites (berserk insanity + earthquake), ignore pain with leech, leap with defense bonus, cleave with dmg rune as main attack, war cry for resist bonus.
Passives: weapon mastery, ruthless, and one defensive, can swap one offensive into -30s cooldown for wrath/earthquake, preferably with better gear if you feel cooldown is too long.
Stacking 5 nv is quite easy and fast, any melee elites die in 5-10s, ranged AI are worse, as they run away, some combos need to be done traditional way (chasing each individual elite). Last clip shows how luring them into earthquake helps, even if few die, it is already much easier fight afterwards. It is important not to attack them with earthquake because then they run away.
There is huge upgrade potential for this character, barely not enough damage to always 1shot azmodan, but it can be done quite easily with better weapon or stats.
Items are mostly rare with resists, stats, crit and ias. Slots with uniques are just temporary, waiting for better rare (helm, ring).
