I played on Azura for the first time ever just over a week ago. A group drops like 6 comets, 3 bat swarms then complains about the lag.
I'm not saying it's the players fault, but holy crap all that AoE completely rekt it. After it happened it would take me 3 and half seconds to weapon swap, and the gameplay was like a slideshow.
I went back to Blackwater where comets don't exist and lag is pretty much non-existent. Azura truly was a terrible experience in both server performance and nuclear bomb squads.
