I enjoyed re-adjusting to the new physics that Feng codes when new exciting upates came out.
I'm not sure if this is even a tutorial, I guess I would call it tips on how to improve and get more efficient kills with high damage.
I think the latest update is great, and now that we can see a little more below us, we can strike from above.
Gas control and precise 3DMG performance is key, and in order to get badass kill like in the anime, you have to practice.
most of it is just getting used to how the game works.
In all honesty, the only way to get Pro kills is if you master positioning.
I really wanted to control jump/gas with "spacebar", because personally I found it hard to control the gas precisely with "L-shift".
And now I changed my key configuration - I control 3DMG entirely with the mouse.
Below, I focus on where/how my character is moving. Levi's special is determined by the direction/speed you are going.

I wanted another way to position my character mid-air aside from the hooks -
GAS control is an excellent way to fine tune your positioning.

As you can see, here I used the gas to veer around the titan when it turns to face me.
A lot of beginner-leveled players pay too much attention to their hooks and where they are hooking - they most likely miss the kill on the first try.
A more experienced player will focus more on the positioning of his/her character and will be very selective as to when to use hooks and gas. See how it moves your character when you hook in certain positions and certain different timings.
There are more experimental-players who really push the limits of the physics in this game in order to achieve a more crafty, smoother kill.
My examples may not be the best, but it shows how it's much faster and easier to take down titans if you pay attention to positioning.
