I was finally able to connect to someone in a player match and they were Chloe.
I think we played 20 games and the Chloe won all of them.
I feel like I can't do anything as Shaheen.
Someone help
Aw snap I think that was me... Green hat, green pants Chloe? A lot of those rounds were close. I think it came down to the last round a few times right? Don't be so hard on yourself. I played a long set against a Bryan player that creamed me 9 times out of 10. Very frustrating. I spent an hour in training and I think I can recognize/punish a few more of his moves now.
Take your character into training Shaheen vs Shaheen, then look up his frame data. Then go through his move-list to see what's punishable. It'll help you understand your character so you don't over-extend yourself. Then do the same with Chloe.
Hope that helps give you a starting point. Just take things slow.
EDIT: Some things I've noticed about Chloe:
-She has a crazy amount of launchers an counter-hit launchers, like oh my god.
-Because of this, almost all her moves are 15frame + start-up.
-She doesn't have a 13 or 14 frame punisher (besides WS1,4) so other characters seem like they can get away with a lot of risky stuff.
-I feel like she really has trouble getting in, since her offense is lead mostly be 1 or d/f1 or 4 or a high-risk/low damage low.
