First - smartasses making power smuggle runs early in the morning, when there are like 40-50 people playing.
Second - lolwuts on 5'kers smuggling anything anywhere with any ID "coz 'ts PROFITABLE"
Third - today smuggling is less dangerous than regular trading - pirates are usually sitting on "bottlenecks", lawfuls sitting on a jumpholes are endangered species.
Fourth - smuggling is way much more fun.
So, I think that x3 and especially x10 wouldn't bring us anything good, but prices on some trade items, like cardamine, should be revised. Counterfeit software runs are WAY shorter and safer and profit is the same, but all this are up to balance team.
