"Being a temporal singularity will most likely lead to becoming a being that transcends time. Beings with Temporal Transcendence only exists in one point in time as far as I can tell, the users of Temporal Transcendence only exists at one point in time."
Sorry, but that's.....not what Temporal Transcedence is at all. Temporal Transcendence is to exist beyond the concept of time all together, not "existing in one point in time", if you're existing in one point in time, then you're not transcending time.
The only thing that was on Temporal Transcendence that had anything to do with it was literally a text that was straight up copied from Temporal Lock, which made no sense being there. So if anyhing, Temporal Transcendence being replaced by Temporal Lock is what makes sense.
