Warlords Of Draenor: Heroic Grimrail Depot Guide
Rocketspark and Borka
The first boss of Grimrail Depot is a duo. Railmaster Pauli Rocketspark, and Borka. Think of Romeo and Juliet (Kara) when you do this fight. While they don't need to die at the same time, Rocketspark will gain 10% extra damage every second after Borka dies. Your best option is to focus Rocketspark to at least 25% before killing Borka. Occasionally during the fight, Rocketspark will jump up to an unreachable location where no one can damage him. Wait for Borka to charge the spot he's at and knock him down to resume damage.
The second boss, Nitrogg Thundertower, is in my opinion one of the most fun bosses in the group of heroics for Warlords of Draenor. Begin the fight by simply damaging Nitrogg where he stands. At 60% health, he will fall back to his Assault Cannon at the end of the car. At this time the walls will fall down and the cannons on the side will spread out. Simply go to the middle, line of sight Suppressive Fire, and kill the adds. Designate one person to pick up the Blackrock Mortar Shells from the Blackrock Boomers. Enter the Turret to heavily damage Nitrogg's Assault Cannon.
Skylord Tovra is the last boss of Grimrail Depot. She requires positioning and paying attention to the ground for her mechanics. She will ocassionally cast Freezing Snare at a random party members feet. Avoid hitting this as it will freeze everyone in a 10m range of yourself. As the fight progresses Tovra's drake will drop pools of Diffused Energy. The tank needs to move Tovra out of these and away from Spinning Spears and Freezing Snares.
