Hello, this is a trick to reduce your WoW ping by around 150ms
Go to regedit and find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces \
Then find the right interface which contains your IP address
Right-click in the right hand pane and add a new DWORD value, name it TcpAckFrequency, then right click the entry and click Modify and assign a value of 1.
Reduced my ping by around 150ms.
