Application pre and post:
Most inconsistencies, latencies and issues I was able to bypass using Pingzapper. However, post migration, I've found the rerouting service to do little to nothing to improve the gameplay's experience. I found I'm no longer able to double weave oGCDs on BRD and sometimes have to clip DoTs as high as 4 seconds to ensure I do not suffer a complete drop and even larger DPS loss. It is incredibly frustating to find yourself unable to play a class to a degree you were previously able to do.
