BG Timer needs Adjustment

Hello, I couldn’t find a space to make a proper suggestion or complaint.
https://eu.forums.blizzard.com/en/wow/t/blizzard-complaints/21552/ was the closest thing I could find and yet Nenyasqi still did not do a great job at explain where this option is. It should be as simple as writing in a ticket or report in game and not having to copy a link or redirect to the web. My complaint is the amount of time it takes to get a DC from a epic battleground. I literally died and went to refill my water bottle and I came back and I was DC from the game. I live in a studio apartment. It makes no sense that within 20 seconds someone gets DC. Please let me know how long I was gone for and how long the timer is. And where can we complain about the timer being too short and unfair. Thanks.
