Yeah, I agree! I love fated lovers and stuff because I love the romantic idea that there is a perfect match for you out there, but it feels like lazy writing when it's only used as a plot device to force the characters together. A relationship is more than the attraction they have together. How are they communicating? Do they trust and feel safe around the other? The power imbalance in guideverse, omegaverse, and domsubverse (the worse of the bunch) sucks because there's always a victim where they are forced or willingly give up their autonomy to stay in the relationship. I think when the plot and world building is simplistic and lackluster, a shitty, toxic romance becomes obvious. Did the author even try or are they just using tropes?
I see that Guiding the Eccentric Tyrant is on your list that one is pretty good sci-fi intergalactic space stuff with guideverse but both espers and guides have the power to fight.
An omegaverse I love is Turning. The romance is very slowburn but is so satisfying. This story deals with a world where magic, divine power, and sword aura exists but then another power emerges. People start awakening with special powers and manifesting as alpha or omega. At first, it felt thrown in there BUT it becomes an integral part of the plot as MC tries to prevent the world from ending and make life better for everyone. I got started with the webtoon and continued to the novel. There's just this deep understanding and respect between the leads that I love so much. It's amazing I can't recommend enough. ٩(๑❛ᴗ❛๑)۶
In terms of "no romance" action stories, ORV and S-classes That I Raised are splendid in system and world building.
I dislike the guideverse. There are some guideverse's out there I like but a majority, to me, just aren't it.
I like system/dungeon (in general and BL) because of the action/fighting as well as the weak to strong/hiding how strong they are tropes.
Guideverse's don't really do that, they're like a slightly better omegaverse. More often than not, it's just one character manipulating the other, playing tricks on them, or straight up forcing them to do something they don't want to do; it reminds me all too much of a bad company/office drama with the power imbalance and blatant misuse of authority.
Obviously if I don't like it, I won't read it, nor will I bash on any particular manga as it is popular for a reason. I just with there were more system/dungeon BL where the romance isn't a priority, or, at the very least, is incorporated into the overarching plot in a way that doesn't distract from the main objective.
