Corrosive Acid 
Avoid Corrosive Acid by positioning melee DPS bots behind Ambassador Hellmaw. Ideally, melee bots will automatically position themselves behind the boss (if they're using the behind strategy), otherwise you may position them manually using
/gr @melee @dps guard
/gr @melee @dps rtsc select
/cast aedmBlackheart the Inciter
Incite Chaos 
Incite Chaos WeakAura
Shadow Labyrinth WeakAuras for Blackheart the Inciter ensure DPS stop attacking when after Incite Chaos to make sure tank has time to re-establish threat.
Grandmaster Vorpil
Void Rift 

If you have enough DPS you may ignore Voidwalkers until after Grandmaster Vorpil is killed, if not you'll need to nuke them or they may overwhelm the party. Use the DPS Attack-macro (or mark adds with skull).
Additionally, you may move the tank (and thus Grandmaster Vorpil) away from the Voidwalkers by using
/gr @tank rtsc select
/cast aedmDraw Shadows / Rain of Fire 
Avoid Rain of Fire by moving bots (tank included) manually using
/gr rtsc select
/cast aedmMurmur
Murmur's Touch 

Murmur's Touch WeakAura
Shadow Labyrinth WeakAuras for Murmur moves bots to the murmur-debuffed position when afflicted with Murmur's Touch. If the tank is debuffed, all melee DPS bots will move to the murmur-debuffed position.
Use
/gr rtsc save murmur-debuffed
/cast aedmand press the spot where you want bots afflicted with Murmur's Touch to run.
Use
/gr rtsc save murmur-ranged
/cast aedmand press the ground where you want ranged bots to run when the debuff fades.
Sonic Boom 

Murmur's Touch WeakAura
Shadow Labyrinth WeakAuras for Murmur ensure melee DPS bots move to the murmur-safe position when Murmur starts casting Sonic Boom.
Use
/gr rtsc save murmur-safe
/cast aedmand press the spot where you want melee bots to run when the Sonic Boom cast starts.
