I wonder how many people posting "My route's fine, go find a better one!" will be so happy once their route deteriorates into nothing. Right now, a single player in a large ship is able to have too-large an impact on the markets (IMO). My route is still profitable, for now, but I can already see it's drying up quite fast, and I'm only able to play maybe an hour a day or so.
I think the idea behind this change was good, but I think they over did it a bit. Time will tell if it is what they intended. As it was, with my limited play schedule, assuming I did nothing but grind my trade route (which isn't realistic, I spend time hunting and exploring as well): It would take me almost 3 months of solid grinding to reach "Elite" in trade status (which is a goal of mine). I suspect if this change 'sticks', that goal may be more along the lines of a year or more. It took me many, many hours of exploring to find the route I am working, and I'd hoped to be able to use it for a while.
