Ues DC has been doing years and those tropes have been around long before WFA which is where they get those from.
Just because DC has been doing it or because Cass is shown here doing it doesn't mean that that's how Damian felt or how he would describe them.
Damian certainly wouldn't describe Tim as Cunning, clever or whatever around Batman Inc era since he'd easily outsmarted him. Similarly that period was the closest we've ever come to seeing Damian have any sort of positive interaction with Jason.
Heck even if it was around the Time of BRe [which I guess can't be canon because again ...... that guy calling himself Tim is a whole ass different person]
This is how he thought of them....
The descriptions in the preview are just the way casuals and fans who are reading the comics might describe the Robins. That's not how participants in the stories would describe them.
That's not the view Damian had of them. That never been the way Damian saw them. Why would he when that doesn't line up with his impression before meeting them, once he met them/got to know them and it's not the impression he'd walk away with based on the events that played out up till then.
