While I think most of the plus and negative points have been made around Solo versus Open, one ting I haven't seen mentioned is that it is very, very easy to grind up to a medium equipped pirate ship that will be able to kill anything set up as a trader. The time investment to buy and have money to run/trade a T6 is waaay more than most pirates have put into the game. I will always run Solo when trading, I know I can break any NPC interdiction, and for those rare occasions it seems to bug out I can easily outrun them. Why should I reward your 'easi mode' with a fat payday, and give you the satisfaction of knowing I rely on your good nature (haha, pirate) to 'live'.
I think it is magnificent that FD have made it impossible for griefers to grief unless I, want to run that risk, there are so many games out there that could learn from this. The last thing FD should do is remove or cripple Solo, I will happily partake in Open events, but on my terms and in a ship which I have prepped for the job.
When I am upgrading ships I will often find I don't have enough to cover insurance for the first few runs, I am not going to put that all at risk for a pirate's pleasure. If I die through my own stupidity (hasn't happened yet, but some close shaves), fair enough, that I can live with, but no not so you can have fun at my expense.
I don't call the panic of trying to escape a player, who has a firepower/maneuverability advantage fun, and for you isn't it just like shooting fish in a barrel, its hardly what I would call a fair or challenging fight, but then maybe thats what you want.
Either way, play your own way, and have fun, its a game.
Fly safe.
