The Leveilleur Line?

[Emmanellain]

do you remember where the interview is online? We've all been wondering if and how much time has past. When we asked the dev's we got the blanketed answer of that it was in a time bubble like the Simpsons and the only mention of the passage of time is when they move to the rising stones. Minfillia states in the quest that it has been about 15 years since her father, Warburton's death.

The interview i read a year and a half ago was an old one close to launch when Heavensward was about to be released, the interview had taken place during a convention of sorts. I'll try and see if i can find it again.
Other than that there was a thread about the passage of time before that got answered HERE
When we meet Alphinaud and Alisae they are confirmed to be "sixteen summers old" right before they depart for Eorzea where they meet the WoL.
So if that rule (link #1) applies i suppose Alphinaud and Alisae's models wont change and their ages will remain ambiguously "16-19 years of age" throughout future expansions as our adventures progress, a shame really, I'm really hoping that they consider changing their models in small increments between future patches for immersion.
