before: maximum free 150 coupon/day if you're top 50 and have time to plunder/have alt
after: maximum 150 coupon minus 20 ingot/day if you're top 100 and have time to plunder/have alt

considering the majority of player who really has time to do this every day is top ~70, this system is worse and more money-*ing :@ but iirc they also reward ticket in GNW pack? if that's the case then this is ok but still isn't better than the old one except for the change of convoy reward
