Guild Wars 2 had the same issue in large scale WvWvW fights. There's too many people, too many things for the game to keep track of over a network connection, and as a result it loses data. A lot of it. The problem is that the game isn't putting priority on the packets that pertain to monsters, but instead companions and minions.

The most likely reason this isn't fixed yet is because it probably requires a complete rework of the networking code. It's a lot of work. Doesn't make it acceptable, of course, but just pointing it out.
