Best reason for Solo is so you don't have yo wait 3 minutes to drop out of supercruise at Jameson Memorial.
So much this!
I find myself playing more and more solo of late, simply because I am getting sick and tired of this lousy network architecture (or distinct lack thereof). Pile that on top of my home port (Jameson) being so popular sometimes I cannot ingress/egress without having to worry about bumping into some noob who can't handle the ship they're in, and even Mobius is getting quite tiresome.
I am turning into quite the grumpy Old Guy...
