You just said it yourself, plunder is way better. They have to fix that, atm for f2p convoys give 450-900 coupons a month and plunders 0 - 4500, it's very clear by averages that plunder is at least 3 times better and in best case scenario if you are strong player assuming u defend all SS missions and win all plunders, plunder is 5 times better.

They should lower plunder rewards or raise convoy rewards cause atm being in top 50 i don't see a single reason as for why i would ever choose convoy.

4.5k more coupons a month only available to top players is very bad, like this game already doesn't have a rep for being unfair to newbs they took probably the least p2w permanent feature and made it favor top players.
