I got the impression that they were wanting a vote like in 2007's Legends line-up where it was littered with collector-friendly Legends figures... I thought at that time it worked, but they want it as a complement to CW/kid collectors now and nothing collector-focused, so I guess that's their way of saying, "This line's not really for you at the moment", maybe.
2007 was like trying to keep up with two full lines... Legends had so much good stuff in it and then the basic line was one of, if not the best line ever... That was some hectic collecting at times.
I think right now they just don't want fans involved in Legends much at all. There are figures in it I'll still buy of course (battledroid 2-packs, Snowtroopers, etc.), but I guess we're not at all considered for this line currently.
