The main problem of this event is that it failed to attract both sides equally. There were plenty of powertraders but very little actual Mollys.
Next time I would suggest (along with the stuff I already said)
a) making the event result have a small effect on story, even if it's just fluff about a corp project being delayed / abandoned
b) as Lemon said, remove straight out kill line on transports, it leads to bad experience for traders
c) reduce the penalty for being shot down a bit. 20 million investment for a run is too much and leads to more people hiding instead of giving in to RP demands
d) add incentives in forum titles and maybe equipment for the unlawfuls / best escorts
Otherwise, cool idea with bulk cargo and turning it into mostly a 5ker event.
