See, the problem (or advantage) of the option to choose was that it could be 'abused' to totally keep you out of the stupid roaming instances that pull you into a battlefield when you just want to go across the sector.

When one made a beeline towards you, you could just hit the Cancel button that came up on the Choose Instance screen and not get sucked in.

Honestly, I thought it was a great feature, as most of the time I didn't want to go into those stupid things.
