Alright how about this. You telling me that you've lost to skarlet with baraka tells me ABSOLUTELY NOTHING important about skarlet, baraka, or skarlet vs. baraka. It sounds like you just haven't figured out how to fight skarlet, and therefore don't have the knowledge or experience to comment on the match-up in the first place.
Now, how about we stay focused on particular characters, because sifting through a bunch comments from 10 different characters is going to be a pain in my ass, and furthermore, will make it more difficult for people to really discuss certain characters.
Alright.
My thoughts on kung lao
Obviously vs kung lao you will want to try and keep some distance. Skarlet operates fairly well at mid range with her daggers, which will put you at a good range to not only punish KL for his projectiles, but allows you room to react when he tries to close the space on you. Be aware of his teleport options, when you manage to block one, you should be able to throw a u3, 1, 1, df2- into whatever combo you want. The u3 should definitely be fast enough to launch. I wouldn't recommend df2, or db2, as they are fairly slow in general. Keep him at bay with dagger mix ups when he's rushing you down. Pausing the second dagger against aggressive players can be quite risky. Believe it or not, you will actually have some good success if you can use your blood ball intelligently with your daggers. The ball does massive chip damage, even larger hit damage, and, provided you aren't lower on health, will generally be an overall good option. Your best bet at punishing the spin on block right now is probably dash, b2, db2, dash, b2, db2, dash, 1, df2, 3, df3, ~4, though I would probably go learn a different combo to punish with cause I doubt they will leave the damage scaling even close to the same. KL players who get risky with spin will often try to throw it in between block stirings. If you see the habit develop, I THINK that db2 after your block string will scoot you back far enough to wiff the spin, and will give you a free combo. I'll go see what else I can come up with that might be more relevant.
