I think the main and probably only reason for this is that they want players to log in daily, if only so we can claim the current reward. If all of us log in daily, that surely shows up somewhere in their records and they can go "Look, we have so-and-so many active players on a daily basis, we need to keep the game going". At least that's the only reason I can think of that makes sense from EA's point of view.
Except I'll login daily but I don't do Quests.
I think the one perk with this version over the last is that you have to do the quest, that way those of us who log in, but refuse to take part in the quest, will register. Last time around, we got everything because we logged in, and since we do that we were counted as "participants" in the event.
There are certainly objects among these that I'd like, but I don't feel like doing the quests, so I'd just live without them and take a stand as a non-participant.
