Spriggan Form Thorn Volley with Thorn Totem total server lag-out

[Gillityr]

Given enough Spell Cast Speed (50% or more) and using Thorn Volley with Ice conversion and Thorn Totem summon/explosion, I can cause the server process to lag for several minutes in 4-player sessions, and even several seconds in solo play. All I have to do is hold down the right mouse button where Thorn Volley is bound. The spell cast speed is key to making it happen. At around 75% spell cast speed, and when getting enough procs from Thorn Volley to spawn and de-spawn Thorn Totems (ring of 5) it can delay the entire game up to 3 minutes as it tries to catch up.

Core skill nodes needed to cause this:
Rotten Core
Forested Expanse
Grove Mind
Pillars of Heorot

Also requires a specific Idol (two is best)

Screenshot showing when it starts to occur. Enemies begin to show no health in the health bars, but remain on screen for extended periods of time. This is an early indicator that either the client or the server process is behind and serious lag/delay in responsiveness is about to occur.

Note as well that Perfmon shows very significant packet receive errors any time skill usage ramps up, and during zone loads. Not sure if this is related but it likely is a separate issue based on my testing.

Also note that you need to hit enemies with Thorn Volley. And, if you wave your mouse around to hit the most enemies possible, you can trigger the totem creation/explosion even faster, more likely causing issues.
