Servers disconnect when killing too much.

Whenever you engage too many mobs as a time, such as with a chaos Lich using Contagion ED/totem - on a map with delirium / packsize you lag and then disconnect. It happens on every server in my region (EU). This went from happening occasionally to now occurring non stop. The result is that the map is lost and so is the atlas node.

It is destroying my desire to continue playing the game.
