@Windstar: From playing you, here's what I've seen that you do that seems counter-intuitive and holding you down:
1) You use very unsafe and random moves. BOK should almost never be used and NEVER used in the manual transition as hopkicks will eat that alive, 1,2 is a useless jab string as 2,1 deals more damage, has more range and is 10f, KNK 4 and KNK 1 are terrible (4 doesn't high crush and is -15 on block and will get blocked if expecting KNK2), stick to KNK 3 (for launch) and KNK 2 (for CH baiting and safety, but duckable, hence the KNK 3). 2,2 is NCc but being -15 on block means some characters can simply rape the fuck out of you just for blocking high (Feng can b1+2, maybe df+3?). Forgot what else you used but you should stick to her safe strings (db2,2, df2+3, b2,1+2, b1,4, db1+2, uf3) and her strong punishes.
2) You crouch a lot. Way too much actually. This isn't Street Fighter, this is Tekken. Going low other than when anticipating a low or blocking a string is a pretty bad idea as it's pretty much asking the get hopkick'd or df2'd in the face into a stupid juggle. There are times where I just hopkick'd out of the blue because I knew you were going to try going low.
3) On a related note, you use way too many fc attacks, and Leo's lows are pretty terrible besides FC df3 and db4,1 (on hit only, terrible on block for both). Stick to moving around while standing.
4) You play Leo aggressively, which is a pretty bad idea. Leo has some rushdown tool (KNK transitions are nice, 2,1 is a nice fast string with range and some pushback properties on block which allows you to keep mounting an offense, but she's a turtle at heart. Punish bad sidesteps and blocked/whiffed moves with small strings, but always keep your mind open to take some risks and land those hopkicks (even if they're a little subpar for her) and df+2's.
Feel free to hit me up for a few training matches, I need to keep working on my Feng. I do too many SS4 and hopkicks.
