Nope, still doesn't make sense. I think you're putting too much emphasis on daily events. It looks like there will be plenty of ways to earn them even if you don't play every day.
How can I earn Legendary Marks?
By completing Daily Story Chapters, Weekly Heroic Strikes, and Daily PVP Activities
By dismantling Year Two Legendary items – assuming you don’t have the maximum value of 200 Legendary Marks associated with your player account
So it's Tuesday, 9/15, and I do the Weekly Heroic Strike (I'm probably underleveled but I get it done), I do the Daily Story, and I do the Daily PvP. Even if each one gives a generous 20 marks, I've now got 60 marks - I'm not even half way to being able to buy one new gun, one legendary weapon engram, or one of the Year 2 exotics I've unlocked. And it seems the only way to get more marks is by dismantling new legendaries that I most certainly will want to play with and not shard right away, unless I'm able to play every day to do the story and daily PvP game.
It's a valid concern for those of us who can't play every day, unless there are other avenues that Bungie idiotically left out of their very clear answer this update...
