Okay, I'll just keep trying on the first one.
What I mean with the second bit is in EX you could finish almost every combo with j.DD 2DD > j.DD > 2DD > 214D but in CP sometimes only j.DD 214D will connect or sometimes j.DD > 2DD > 214D will work but not the second half. Plus there are combo's that I can do in both Luna and Dia but only in Luna will the full j.DD 2DD > j.DD 2DD > 214D connect where as in Dia the opponent can tech half way through.
Do Dia and Luna's Drives have different combo qualities outside of damage?
