The strike and Crucible stuff? OK, sure... but I think you'll find it'll be a ghost town for anything but Control and Clash. This is Bungie's way of keeping the other modes ALIVE for Y1 players. Because they couldn't stand alone anymore. The strike thing, I guess so. You're not getting much of a challenge-- and no useful gear-- from any of them anymore, but knock yourselves out. I expect Bungie might make that change, at least. But there is absolutely no reason-- none-- to give Y1 adherents access to legendary marks. The only events that drop legendary marks are events that non-TTK players cannot even enter. And the things you can buy with them cannot be purchased by non-TTK players, either. They are a feature of content you chose not to purchase. So why should you receive them?
