This is a super amazing change to the game. I have multiple times been locked out of the game, because I 90ked while zoning. When that happens, depending on the timing of the 90k, both your server, and the duty server think your on the other server, so you cant log into either. Having a forced logoff is amazing.

(And I am talking I was locked out of the game for 2 weeks while I waited on next downtime)
