If you don't mind ghost, could I give you a concept for a predator i came up with?

well here the Idea if anyone wants to use it.
A pred that stalks through the halls, always in pursuit, making the player feel like they are being fallowed no matter where they hide,
So here are the stats.
Speed when not in chase: slow,
Speed when in chase: High
Chasing skill: high,
Noise when not in chase: quiet,
Noise when in chase: loud
Height: slightly taller than the student model.
Gimmick: The pred is constantly aware of the player location at all times and will start heading towards the player; once pred has spotted the player, they will make an audio cue and stand still. If the player were to stare at the pred for 2-3 seconds, the predator would retreat to a random area, then start fallowing the player again after 5 seconds. If the player does not look at the pred within 5–6 seconds of being spotted, the pred will give chase at an alarming speed.
And of course, if you wish, change anything you like. After all, this is just a concept.
Apologies, I forgot that potentially adding new preds is literally right there in the might add section. Your mechanic idea sounds like it would be the easiest pred in the game, even with two random ones. I think the complete opposite would make for a more challenging experience. A large, slow, lumbering pred that just wanders, but will chase you, quickly, if looked at. Sort of like the enderman I guess.
In two pred mode it would be rather difficult, cutting off areas of the map while you actively try to avoid the other.
These might be too much of a deviation from the stealth focus though.
