Some potentially do have a pc/internet issue at times, you ruling that out for a % of affected players?
Some are for sure more affected than others. It would be interesting to figure out why that would be, rather than just shut down the discussion.
For example, while others in zone are complaining about lag, I either don’t experience it at all, or it’s brief and not serious as they claim. I would have thought all on shard would experience same lag? Maybe not. Could be factors, such as pc issue, connection issue, location issue. Sure, could also be a Blizz issue. But I sincerely doubt same issue for everyone complaining of lag.
In this other lag thread, some are saying lag, others say no lag. Looks like it’s not a general issue for everyone.
Here’s a list of things to try for connection issues.
Here’s a blue response with suggestions for diagnosing potential issues using WinMTR, maybe post a thread in tech support forum.
