Hi Cometageezus,
I am sorry to hear you are still having issues in-game. I also know the forums can prevent you from posting your WinMTR data directly. The good news is Blizzard CS has approved a work around to post your data. I would recommend that you run the test again and post it following these steps.
If those steps have no impact, please run a ‘WinMTR’ network test while the error occurs in-game so that we can further investigate potential network-related issues between your computer and the game server. Here are the instructions:
Download the tool from this page
Enter the game IP into the “host” field. The IP address for our games are listed on the WinMTR instructions page
Start the test and play the game for at least 15 minutes. Ensure the problem happens while the WinMTR tool is running.
After recording the problem data, click “export text” and save the WinMTR file in an easy to find location.
Once you have that made, open the file. You’ll need to copy and paste the contents of the Text document into the post, and put four Tilde (~ ) marks above the WinMTR. It’ll look like this:
WinMTR goes here
