rusty's got a lot stacked against him lol. So many others with the same powerset, generic personality, no distinctive costume and to top it off he's been dead for 30 yrs .. I think character-wise skids is more interesting than she gets credit for but she also suffers from a pretty generic design.
big agree on karma needing + deserving a push but I dont really think Betsy's race had anything to do with her not being used - if the interest had been there behind the scenes they would've found a way . Kwannon's still here anyways and as recently was the last issue Betsy used her TP for a more "ranged" attack and not just to construct her sword + shield
