I'm going to need you to stop tagging me whenever this guy says something dumb. I deal with enough idiots at work and don't want to spend all of my time off correcting them here.
Pretty sure I have NEVER seen a Harley player say she is a good character in the last year. In fact, while she has some obvious flaws, I've ONLY seen Harley mains downplay her to the point where Harley players claim godlike status when they win with her (Though in all seriousness, most Harley players are really good).
You just have an abnormally low opinion of the character and the stuff you say about her belies the fact you probably don't know how to use her tools all that well.

That said @all Harley players, while I can't necessarily disagree you have a low tier trait, your trait is considerably better than the other bad/sub-par traits (Joker's, Cyborg's, potentially Batgirl's, Deathstroke's, Shazam's, Killer Frost's and Scorpion's trait are all worse than Harley's).
EDIT:
Not a chance.
On the flip side though, some characters have gotten high level representation and still find themselves on the low end (Green Arrow, Grundy and Ares come to mind) so I doubt Batgirl would have been out of the top 10 even without Sonicfox.
