Annoying
Oh well, guess I'll have to put the CD in every time I wanna play on B.net then, but one would think Blizzard would realize the CD copy protection isn't what keeps people from copying it.
It's either good ole "supporting a good company", or the need for a CD key to play on B.net, people who don't care for either are just gonna copy the CD and use a crack, and the rest of us will be left with the inconvenience for no good reason :|
