Is it just me or is the sync loss in AV getting worse? It seems like every game lately is just a matter of time before you get one or more of your alts that refuse to recognize that your main is alive, standing right in front of them. Also, I used to be able to resolve this (although it takes a large amount of valuable time) by running away from the alt, or having the alt run away from you, for a while. This no longer seems to work.
I doubt this is some intentional scheme by Blizzard to ruin multiboxing, but it sure is an annoying bug.
