After watching the whole series; i can confidently say that Zeta Division is just plain awful. There is zero adaptation, zero map control, zero awareness, and zero confidence. From 2020 I really wanted Japan to get good at esports: their market is huge and they have so many fans, they should be putting in the hours and the effort to get better. Not to mention some extra personal bias towards them bc i just like japanese culture ig. But despite all of that no, they just continue to disappoint year after year, event after event. In Masters 2, there were flashes of what I thought was Zeta finally learning from their mistakes; which they definitely were, but one common there from their success then, and event now, is that they rely WAY too much on the opponent making mistakes. They are not creating their own opportunities, which makes it trivially easy for any half decent team to just completely annihilate them. What's even sadder, is that it's clear they they have serious talent on their roster. Their players have (for the most part) insane mechanical skill, which is what has allowed them not to get 13-0d on every map.
All of Japan it seems is suffering as well. DNG has so far put on one of the more consistently trash performances I've ever seen, and the Japan Challengers League is full of cracked Russian imports carrying clouted but washed Japanese (who are frankly much worse than what we've seen so far from Japan on the international stage).
In essence, Zeta (and all of Japan) need more brain. They have the aim, but their strats and ability to adapt are criminally lackluster from what should be expected from a top-tier team. Maybe the coaching staff needs to change. Maybe they need to switch out some players. Maybe they need to practice more internationally. I don't know. But they need to change something, or else Masters Tokyo is going to have a really silent crowd.
