Common sense indicates that fightin other players will be more difficult than fighting lackluster, preprogrammed AI. Anyways. I may change my opinion if they implement pvp missions available only in Open (for exaple "Assasinate CMDR X"). If those gonna be Open Play exclusive and lucrative then i wont bother with Solo players hauling fish 24/7.
EDIT: But ,yeah. Solo can farm 24/7 and jump Online at any time... just meh.
Common sense eh ? How many units of common sense ? It's entirely subjective.
You don't have any statistical evidence, no one does. Yet you still want you're way of playing to give more reward than another's. Doesn't sound very fair to me.
