Slow casting speed across all characters

Despite doing all recommended steps by Blizzard and Comcast, proc’ing a mount is a slower casting speed than anyone else’s around me. This has a very bad effect in timed mythics. When I cast a spell, other people see a large gap between casts that I can’t see. I used a button that cast 20 times per second just to test if it’s me. It isn’t. It slows down my DPS an embarrassing amount in my raiding group. It slows down all aspects of gameplay. My ping is fine, my latency is fine, and all aspects of the game have been reset as recommended in my tickets. I’ve gone through this with Comcast the last three moves. I forget what they did is called. Can you think of what I should tell them to do? I put Blizzard on the phone with Comcast once from another house, and Comcast was forced to fix it.

Try this one, spell que might fix this issue. I’ve played in wow with 250-350 ping in PvE and it felt great! It was back in cata but still!

that doesn’t sound like something you should be doing…
