I think a lot of people have Windows 10 these days because many people were forced to update (including me
), so I'm not sure how much it is an issue with your Windows OS as it is with your internet connection. I know that when the connection on my end is cripplingly slow, it sends a message in the battle log saying "Class Data loaded too slowly, you will be booted in 5 seconds" or something along those lines.
Is this what you see in your battle log?
Have you investigated the option that it could be your connection, perhaps throttling or being disturbed by something?
How often does it happen to you?
