do your daily hunts while this happens? it's a nerf but pretty minor for anyone who does less than 3 hours of hunts a day.
a slow down on the people getting sand/oil is a good thing. because of that down time from all the A ranks being zerged, this means people will actually do other content in game, or maybe even go into SCOB /gasp. while the people going after all A ranks will still get seals at around the same pace, there is going to be a gap in time where they have to do something else. most people i know got thier hunt fix pretty fast, myself included, and hunt on and off. now i typically do other things and grab hunts in the smaller zones.
Only if you spread that out every day. If you did 5 or 6 hours a week, but only on 1 or 2 days, its definitely a nerf. I got like half my seals from Bs (I've only ever killed like 3 S's, never on when they pop). Huge nerf for those with less flexible playtime. If you can hunt a few hours _every day_ maybe its less of a nerf, but thats not everyone.
Sorry, going to have to get your welfare gear from hunts still.
