I feel like they have been doing fine. MInd you if it comes to an end fast, yeah, GET THEM OUT THERE.
If we really werent getting all the non variant characters, that would have to be rectified any way possible. POP is (obviously?) second only to vintage MOTU.
If it takes a POP sub in the year 2015 to get all the main characters (not variants) from the original toyline, and a few important FIlmation characters (Bow, Scorpia, maybe others ect...) do it.
