How do you even learn to play this game being this far behind

I've been on the fence considering buying the game since the launch because I didn't see a character interesting to me until the La Reina trailer was shown. I finally bought it about 2 weeks ago, and it's been a pretty infuriating experience so far trying to learn. The people I have access to can't teach worth a damn, or the way they teach isn't for me. I'm wondering about some methods on how to learn this game because I find enjoyment in this game despite the nonsense some of the characters can do to me while I don't know how to defend against it. I'm really looking for fundamentals help given my relatively low interest in the rest of the cast, but I have been pushing everybody to 10 for the premium currency.
