I'll have to take that suggestion and pretend this is a memory! That being said, I don't think it would have been that complicated to make an alternative without Estinien - there are other Dragoons in Ishgard!
The reason I felt a bit disappointed is because there are plenty of npc's that have changed dialogue during and after Heavensward. I was hoping this attention would be brought to the job quests, though of course I do understand that would be more complicated than just changing a line of dialogue - but not by that much! They could have changed the name of the character without having to touch the model much. Could have changed a few lines of dialogue to place it in another context.

But of course, story isn't as linear as that either - as stated above, what if someone played half the dragoon job, finished heavensward and came back?

In other words I understand though that doesn't necessarily mean I'm happy with it. As silly as it sounds it would be a lot more bearable if there was an "echo" animation playing at the start of the job quests!
