Well, that problem is with your Leader .. If you find him too greedy and don't appreciate the things you've been contributing then maybe look for other groups that will give you a fair play and deal when it comes to that kind of matters .. Aside from that, maybe your group have this kind of rule like "Legendary Packs Rotation for Distribution", if you already got 1 Legendary on the past week then you will get other kind of pack on the next coming weeks so that other members will also experience Legendary .. But if not the, thats it .. Try to talk to him or if you cant take it anymore then move to other group and enjoy playing ..
