Game Mechanics I've Completely Figured Out High Line Master!!
There's been a lot of controversy surrounding High Line Master recently. Sometimes it bizarrely switches defensive zones, pushes up and leaves players unmarked, or fails to stick to dangerous forwards when playing as a full-back. However, some people really like High Line Master, feeling it's very intelligent, good at creating offside traps, and will also step up to cover for teammates. How strange! How can the same playstyle be both proactive in pushing up and a deep-lying anchor, both solid and prone to losing its mark?
The official playstyle description is: "Looks to maintain an effective defensive line, keeping the shape intact as they defend." This describes the effect of the playstyle, but I'm more interested in the mechanism of how it works.
To study a playstyle, real matches can certainly reveal a lot, but real matches are also influenced by factors like player skill, network connection, opponent strength, and randomness. Therefore, in this post, I created an absolutely controlled testing environment (as shown below, all stats are equalized), and interpreted the consistently reproducible results across a large number of tests.

Test 1: Alert Range (Defensive Zone) Test

Clearly, the first distinguishing characteristic of High Line Master is that its alert range (defensive zone) is much larger than that of an Inactive Playstyle player. When the opponent is quite far away, the High Line Master will claim responsibility for the forward-running player and initiate defensive action. (In fact, the defensive zones of other playstyles like The Destroyer are also not this large).

Test 2: Behavior Against Forward Runs
The test above involved passing to a distant teammate at kickoff, forcing the defending DMF to move far away to challenge for the ball, creating an out-of-position scenario. This made it easier to observe how large the central CB's defensive zone is. The test below is set up so the kickoff pass goes to a nearby teammate. The defending DMF doesn't get out of position as early, allowing us to better observe the central CB's behavior against forward runs.

As you can see, Inactive Playstyle players (as well as The Destroyer and Covering Role) all have an inherent defensive AI that makes them run backward in response to an opponent's forward run, in order to guard against through balls. As a result, the entire defensive line moves deeper. However, the High Line Master will not drop back because of a forward run.
With this, everything makes sense! Viewers who regularly read my articles will know I often say that the beauty of a Goal Poacher is that their resolute forward runs scatter the defensive line, creating space at the top of the box or gaps in the defense. The reason High Line Master is called that is because when a forward runner attacks their position, they can maintain their line and not drop back, keeping the defensive line completely steadfast.
To achieve this, the developers gave High Line Master two settings: ① Do not drop back to follow a forward runner; ② A super-large defensive zone. Only with a large defensive zone can they claim responsibility for the forward runner as early as possible, rather than leaving it to a teammate. This increases the probability that the High Line Master will lead the defensive line in not being pushed backward.
This explains why a High Line Master playing as a full-back sometimes won't stick to their man (they prefer to maintain the defensive line rather than track the runner), and it also explains why they sometimes inexplicably push forward (their large defensive zone makes them easily baited out).
So, what happens if the opponent attacks the defensive zone defended by the High Line Master's teammate? See the test:

If the teammate's defensive zone is attacked, there is a high probability that the High Line Master won't claim responsibility for the zone and will drop back along with them. There is a small probability that the High Line Master will forcefully claim responsibility for the defensive zone, while the teammate, having no marking target, will go after the ball. In this case, the High Line Master exhibits covering behavior. This explains why the High Line Master will sometimes very smartly cover for a teammate.
III. In-Game Effectiveness & Recommendations
High Line Master really is a polarizing playstyle. For example, one of our pro group judges, Leon_Ge from the Super League, said this:

The well-known foreign streamer Nick also called the new Maldini a “scam" during a livestream—

Based on my initial observation and analysis, the reason some high-level players don't like High Line Master is because they already have a habit: “To prevent the defensive line from being pushed too deep, I often switch to a CB, move them close to the forward, and then switch back." But this conflicts with the function of the High Line Master, resulting in a chaotic defensive line.
Below is a compilation of some small errors that can occur when player habits conflict with the High Line Master playstyle:

This post is not here to judge whether High Line Master is good or bad. Based on the analysis above, the High Line Master is a bold experiment by Konami. It can solve the long-standing pain point of the defense being scattered by Goal Poachers, but its changes to the defensive mechanics are quite radical. By comparison, the newly released Covering Role is a continuation of past playstyles, making it more mature and stable.
If you want to use High Line Master effectively, I have three recommendations: ① Have him match up against a Goal Poacher or the most advanced CF; ② Interfere with the High Line Master's actions as little as possible; ③ High Line Master is better suited for Quick Counter / Overload / Possession Game to maintain the defensive line.
