I can understand why they don’t want to give too much information about timer of spawns.
But in the same time I agree with the frustration that can come from it (even if it’s working exactly the same in pogo so it’s not new)
A suggestion could be to add a special symbol on top of the Dino like a “!” when he’s about to depop, like during the last minute or last 2min. This way you still don’t know exactly when he’s going to depop but you know if you have to dart him from a distance or if you have time to walk.
But maybe it would be still too much information since you can extrapolate despawn time (unless randomized in an interval)
