Conscripts would undoubtably return home, since they would still have farms that needed tending to.
And until we have some additional info on Red Templars, and the situation in the Dales in general, then I would say we MIGHT want to postpone the handing it over to Elves and leaving the inhabitants there to genocide.
*bangs head against the wall* You are not listening.
No one has EVER said that the humans would be victims of genocide in the Dales if the elves took over. Lobsel said he doesn't believe any civilians need to die, I have said that I don't see any reason why the elves can't take it back humanely as the humans are abandoning the Dales as a result of a human civil war, add in that there is an elven rebellion already going on.
Giving them land may actually be a large step to restoring world peace.
Facts of the world as of now, the end of Asunder are
1. Orlais is in a civil war between Gaspard and Celene
2. The elves in Orlais are rebelling
3. Mages and Templars are at war over idealogical differences and where mages exist in the world
4. The Chantry has lost control of all its armed forces.
5. The humans in the dales are leaving the Dales.
This seems like the best time to give elves their land in a humane, no-killing-lots-of-people fashion.
