Getting bored in a ranked match and just trying to red-parry the entire match.
And ending up losing…
Favoring one set of normal attacks over others, just because I think it’s their strong points, and inevitably get punished for my stubbornness.
Like only using kick attacks for Chun-Li, while still knowing she has some very nice punch attacks.
Also, constantly charging/turtleing with characters centric to charge moves, and barely going on the offensive.
my main one, by far, is going for throw/non optimal punish after a parry too often. i consider myself quite good at parrying but a lot of times i end up punishing with throw/a hk instead of cl.mp (as oro) and throw instead of low fd or st back hp or st cl. hk cancelled to super (as chun)
id win A LOT more than i already do if i could always maximize
I spam hadoukens, try to counter with shoryukens at wrong times. I said to myself last night, I should keep a damn journal on me when I play this game and note all the times I’ve been worked. Oh and settling for matches that have shit connection which is 99% of the time.
I need to stop waking up and playing at 4 am lol. I try to parry everything and drop combos a ton since I started playing after the 2 year break.
I do a low parry attempt too much after blocking a jump in. I’ve gotten better at not doing this so much and going for an alternative as soon as they blow it up once though.
Also I give up ground or back myself into the corner way too quickly at the beginning of a round in this game. I usually don’t rushdown unless I’ve landed a knockdown or something big.
I just give up when the game’s too laggy and let them hit me without touching my stick, looking pretty stupid.
I only ever get salty online, with lag and stuff.
Doing b.HP with Alex and then follow it up with EX Shoulder. Works more than it should. Also doing EX Shoulder when they’re playing runaway. That’s about it. In addition to posting on SRK, that’s another bad habit.
Never punishing with a jumping attack of my own when I air-to-air parry, I just let me and my opponent land and then attempt to throw them.
Also, trying to throw everytime I parry an jumping attack.
I do that too sometimes.
You too? 
Trying to parry on wake up as Makoto. Sometimes it’s not a bad idea when you’re fishing for a karakusa, but often it gets me into trouble. So I’m trying to block more. Also, not being able to QCF better when I’m on the left side. I’ll stick out a normal trying to super cancel, but I’ll get an uppercut instead which totally screws me over.
Getting completely mindfucked by Dudley… Riot Guard and HARD_BREAD, I hate you.
Seriously, can’t even count how many people I’ve beaten with Oro with cr. mk xx command grab on wake up 3 times in a row, they get stunned, then they die. It’s sad.
Remy- Crouching MP/lk cancel low lov to escape corner pressure…
Some people that are way better than I am just bait that shit and fuck my world up(speaking of which, I wish I knew when I could bait parries with Remy besides reversal parries)…
Losing.
But yea, not exing enough, abusing one move too much. Sweeping too much, but sadly because it works a lot.
And just remembering the matchups, I get into the corner and if I’m on the defensive I usually lose.
definitely jumping into kara throws.
Getting hit seems to be my worst habit
trying parry on wake up frequently.
effective against 95% of the online population.
