I have not come across any in era evidence to suggest rooting in place.

However... i did find mention from out of era leash testing that ToV had a much shorter leash than 500 units (i think that is what we were told was put in? ). If this would be accepted as evidence, I'm not sure how this would affect "pull to zone" tactics. I don't know how sensitive the leash range is to that, perhaps pulls like we see weren't feasible (at least on some dragons).
