I just finished my little project on this topic
I got this idea since arcane bore was included. Okay we had to raise the maximum amount of frames being moved on this server to 2500. I don't know how much frames there are in fact but there are much more then the standard 1000.
The Problem that i'm facing starts while depleeting the nodes completely. All is fine until the aura network is "working" and tries to refill the used nodes. If that happens the complete server is going laggy :/ Anyways it looks geat firing at least 4 arcane bores
