I'm lucky enough to be in a group with so few players that I have too many packs XD so if y'all want like 3, I'll trade you for some more coupons... XD eh
Honestly packs are the thing that I imagine splits groups up more than anything else. It's a pain to keep track of them and everyone feels like they deserve one. I think that giving packs only to "core members" could work in some cases but not in others; it depends on the mood of the group I guess. I dunno, at my last group we went by participation first and then who had the least refines second. And that worked for us but there's a lot of systems out there. To keep people happy, we'd sometimes have to count on some of those "core members" relinquishing their pack privileges (like people who buy seals, or people who don't care about them) so that we could spread the love a bit.
