It's impossible for top-tier powers like the Four Sects of Wutai to not have transmission arrays.
However, their powers are so immense that the transmission arrays accessible to outsiders are typically placed far away from the main sect. After all, if anyone could teleport right in, how would they guarantee the sect's safety?
Of course, the transmission arrays within their sect are beyond discussion—those are for internal logistics and unrelated to the outside world.
As for the external transmission arrays, not only are they far from the sect, but they also require a strict assessment of the qualifications of users before granting access.
For a major power, this is a basic requirement. But for those being transmitted, it feels highly unfriendly.
In short, the ones frequently using the transmission arrays are the familiar faces; new ones trying to enter find the threshold quite high.
