Akkadius, not sure if it's just in HW zone, or if other people are having issues elsewhere, but I, and some guildmates have been experiencing random disconnections both during, and in-between pulls. I typically never have connection issues, but at this point I can't stay connected more than 20-30 minutes with going linkdead. Just something to check if you have time.

I've been experiencing this as well. Also seem to get desynced form the server fairly frequently, only in HoS. Drac
