The difficulty of synching game entrance

[Drasca]

In guild wars, when yourself or allies are on the "loading screen", their characters don't physically show up yet, and are pictured as 'greyed out.' The client is loading everything in the backround while you yourself are looking at a loading screen. The server recognizes your client is 'still loading' and your character does not show up until you have.

Desynchs are still possible, but at least entrance/exits of areas aren't so fubared.
