Unfortunately, the game apparently starts to perform poorly depending on the size of your builds. This is one of those things that's keeping me from going crazy with my builds, as I would prefer the game not lag in the event a high-difficulty raid happens while I'm doing anything.

Would be utterly fantastic to try and fight off an army of Wolves or Fuling while your FPS has been cut in half simply because you built something large.

I sincerely hope the developers can iron out some extra performance in regards to this soon. :)
