Sorry, but Daredevil is a classic A list character at Marvel.
JJ is not even in the same alphabet.

She actually just got a new series by the original team that created her! First issue dropped Wednesday, and it's pretty damn good! I would recommend it if you like the show at all.

I'd say DD is either a high B-lister or low A-lister if that makes any sense. However, Luke Cage has never been higher than a B-list character even in his heyday. JJ was always pretty much a C-list character. Also, I wouldn't call it "lucky." It just makes sense plot-wise to make shows about these characters and their upcoming Defenders team-up show given the characters' location and the type of storylines they're often involved in.

was the character lucky enough to be part of the MCU on Netflix? do you see Luke Cage or DD being B list heroes?

Probably has gone up just a bit but nowhere near as much as Tony Stark. So I would say she is probably a C-List or B-List at best.
