I'm looking for a word that describes an attribute Y, where you could say
The good thing about X is Y, the problem with X is Y
note that it's not a neutral attribute, it's simultaneously good and bad.
is there such a word in the English language?
preferably I'd like to be able to say something along the lines of:
Y is a ______ of X; it's good because of blah, but it also causes bleh problems
