Yeah, you can't delay spawns (of NPC's nor teammates) with DelayCommand.
Which do require Fallen Guardians solution.
I used it for example on the Telos cantina. One dancer got destroyed, the other spawned, but doing that at the same time like OE's script did would move the dancer away at spawn since the original was still there. Adding a small 2 seconds delay would allow her to remain on the proper location. However, yeah, doesn't seemed a way to do so unless with an executed other script.
