Reread again what they said. They know that shadows are actually giving problem so in 1.4 they are upgrading the shadows to fix this, they never said anything about super servers.
My point is Server Lag is a much bigger issue then Shadows, but BioWare work on Shadows first and that is crazy.
You fix the WORST issues first not the fluff issues first.
Entire Ops or War Zone freeze for 3 seconds is worse then bad Shadows. I was pointing out the asinine priority.
