Mechanics

Overview

With 10 million hit points and a six minute soft enrage timer, this is fight for a large group of players, likely 24. Based on the mechanics, damage output and the fact that this encounter does not take place in a phase, the Lance Squadron Command Unit should be viewed as a new 10-Stack Dreadtooth for decently geared Level 60 players.

Suggested group composition is two tanks, six to eight healers, and at least ten DPS.

The battle with the Lance Squadron Command Unit takes place on a platform overlooking a ravine. The platform is open on three sides and anyone knocked off the platform and into the ravine will be instantly killed.

All Roles

The Orbital Missile Battery and its five roaming targeting circles are active for the entire fight. It is important to not touch the targeting circles to avoid Air Strikes being called in that could hit you, or another group member. It is critical that if you are in an Air Strike, you immediately move out of it as the 30 meter knockback can easily throw you off the platform to your death in the ravine.

No player should ever be within 5 meters of the space between the walker's feet. All damage from Poisoned and Explosive Charge can be avoided by keeping a safe distance.

Tanks

The walker should be tanked so its back is to the ravine. This protects the tanks from being knocked off when they receive the knockback from High Impact Bolt.

The walker does not have a standard cleave. Rather, the AoE effect that surrounds the tank receiving High Energy Beam means that no one should be standing within 5 meters of the tank that the walker is aggroed on.

A taunt swap is performed after one tank receives 10 stacks of Melted Armor from the High Energy Beam. This is not mandatory, as a tank can be healed though 10 seconds of 0% armor, but it’s helpful to the healers to perform the swap.

Healers

Special attention should be paid to the tank the walker is aggroed on, especially when they are receiving Melted Armor stacks from the High Energy Beam, and as they are waiting for their 10 Melted Armor stacks to fall off, as they have 0% armor during that time.

The Poisoned DoT ticks very hard over its five second life. It should be immediately cleansed from any player that picks it up.

Periodic group-wide damage occurs from the Cluster Rockets which can be easily recovered through HoTs.

The soft-enrage can be healed though, even when damage output is increased by 200%. Players being hit by Explosive Charge or Poisoned will likely be almost instantly killed.

DPS

The Orbital Missile Battery is active for the entire fight. DPS numbers will be lower than what players are typically used to achieving due to the frequent movement that is required to avoid being targeted by the Battery, or to move out of any Air Strikes that players find themselves in.
