I agree with you on this, though I believe problems stemming from a lack of coordination or experience (possibly skill depending on the player) are much more common than the lag issues. Don't get me wrong, there are people who genuinely have issues with their connection and it's understandable. It does make it harder on the player experiencing the lag as well as the people they are grouped with. But in my experience the bigger problem is people lacking raid awareness.
