Evidently, the lag in the Mires is a well-known issue and is actually attributed to an over-abundance of shield drones in the area. Shield drones are small flying robots that hover around groups of Bane and cast a protective yellow bubble around all those who stay within its radius, shielding those inside from most damage. A typical strategy when faced with large groups of Bane and their accompanying drones is to first target the shield drones with EMP weapons to lower the groups defenses, before moving on to assault the larger force. What has happened is that the AFS NPCs who engage these groups of Bane as part of Tabula Rasa's unique persistent warfare, lack the skills or know-how to take out these shield drones. The consequence? The Mires is absolutely covered in small groups of shield drones with nobody to protect but themselves. These wandering shield drones are responsible for the two second lag between when you hit the trigger and when that sonic missile leaves your launcher. Bah humbug.
As if we didn't have it bad enough already, I've seen many players blast through dozens of groups of Thrax and Kael, only to leave half a dozen shield drones in their wake. And we wonder why there's lag! So I'm putting out a call to everybody who finds themselves questing in the Mires: clean up your after yourselves,
