It's too early to say but I wouldn't bet on it myself, she does have some matchups skewed in her favour though. It'll be a harder match if you aren't using your character's best options against her flight and are unaware how to defend against her ground game, that I know for certain
Was that me?
I'm on PSN at SpehSpeh. I know I've seen your name before on some PSN lobbies but don't remember if I've fought you or not. My last KOTH win streak with her ended at 37 
This is true...but she is so much more than just some character that can fly and fly away. She can compete on the ground plus her B2 mixups are great. HawkGirl players that show strategic/smart/ and fierce air execution are too be feared in this game...imo. Air mace throws, MC, and Stomp can all give experienced players serious trouble. NO ONE in this game controls the air the way she does...air spacing is so essential to the complete package with this chick. Just my .02 cents
That's the truth, against people that don't know the matchup she's seen as god tier, but in reality once the dude knows the matchup (such as the batman I fought in those grand finals), it becomes much harder for us to open peeps up with her. It's not impossible though, just very hard. Imo she's gonna be mid tier at best, low at worst.
Omg its SpehSpeh! I played one game with you last night before i rage quit. GGs!Was that me?
And yeah, I feel like a lot of the wrecking face going on right now is due to just inexperience with matchups. She definitely doesn't feel high tier right now but she also doesn't feel as low of a tier as everyone seems to think.
I don't see her getting much attention. She doesn't have anything "broken", aside from the -55 on Mace Charge being incorrect. I would LIKE to have a better close-combat set of normals, such as 22 not being awful slow on start up and short on range. A lot of her strings hit high, which is annoying because everyone likes to crouch guard, but is also nice because jD2 is so fun to land 6 times in a row.
Mace charge is safe on block, at least for now. It's "suppose" to be -55 on block, but it's no where near that. Wing Evade is a possible wake up option, but it can still be clipped out I believe with chaser attacks (assuming Hawkgirl doesn't do a follow up to it). I would imagine her "weakness" is simply jumping attacks after a knockdown. If you cross her up, Wing Evade likely won't come out and Mace Charge will whiff and should be an easy punish.
Wishlist:
Ideally I don't think she should be attacking high that much?, she has solid overheads especially WE2.
The price for having a safe advancing dive kick. lol
Adding to this, you can even get it off a simple d1 with d1xx fly d3
It's still not even -8. There is nothing that can punish a blocked Mace Charge except for Green Lanterns Latern Might, and even that isn't consistent.
Because she has to get pretty much right in their shit to start a real offense, which isn't always easy since her approach is fairly shitty outside of evade 3 to get in (Which has really fast recovery but is still -), many characters have more damaging direct mixups up close, and it's not especially difficult to end up giving the opponent momentum, which is not something she wants when her average damage is relatively low aka eating 50 damage from a good Superman because he blocked divekick or sweep. Not saying she shouldn't ever go for it, but if you're playing Hawgkirl mainly to rush them down then you're playing the wrong character. Evade is great against characters that can't already keep her out and throw long range shit as their general gameplan, but its options can still be blown up with a good read or just strong horizontal space control. The more people learn how to punish her individual options and convert into as much damage as possible off random air hits against her, the smarter HG players will have to be with her tools.
while her good strings, start high.
