The persistent lag freezes and resulting deaths from them have really detracted from what otherwise might have been an enjoyable expansion.
I'm so friggin sick of the lag deaths that I really don't even care about Ravenloft anymore. Even when it's not actually frozen there's enough constant lag that it feels like I'm playing on a 2s delay. It causes problems with timing of abilities, makes heals not land, and on and on.
It kills the new content buzz. It's like being randomly kicked in the sensitive bits while opening Christmas presents.
It's ridiculous. Fix it.
