Correct; but you can prevent the DC that comes with it.
Whilst I don't entirely understand why the DC happens (it seems even Blizzard don't at the moment) it is completely preventable, but as I said, most people are too proud to do so.
The DC's only happen whilst mouse turning. If you go into Ruins or RoV and go to the edge of the tomb, or go to the pillar as it's rising and touch it whilst mouse moving, you will DC. However, if you do the exact same whilst using QWEASD ("Keyboard turning"), you will not. The way the DC works is very similar to how you used to DC if you span your mouse around whilst holding left/right click.
The way I look at it is simple - If I DC, we lose the game. If I keyboard turn when near pillars, it may be looked down upon, but at least I'm still online.
