Plunder have a much better deal than convoy already, that's a fact.

I am salty about it because I CHOOSE to not plunder, because I feel it's wrong, and as such I am punished by reduced reward.
I don't get plundered very often because there are a total of 2 or 3 people who can plunder me.
I could have easily plundered because there are dozens of easy plunder targets for me.

Part of the reason I guess is because plunder is horribly OOC for knonoha ninjas. If I were playing as a missing-nin, I probably won't have such an issue. I am perfectly fine with playing as the bad guy, but doing criminal actions as the good guy... just no.
