Believe me, for all those who complain about plunderers you aren't thinking about what the plunderers have to go through. It took me over 2 hours to get 3 plunders. I sat there from the time the event started and I only successfully plundered twice. So in other words I spent 2 hrs and 15 mins to get 100 coupons.

If you are smart you can increase the chance that you will convoy successfully, if you go into it haphazardly you're going to have half your coupons taken away. This system is perfectly fair for the amount of time it takes someone to plunder when you can complete an entire 4 convoy runs in 10-20 mins.
