soo are the dragons really the enemy?

[Celvantis]

There has been a tad much of straw clutching to debase one side over the other for a while now but it is no secret as to where the conscripted men went.

It is highly unlikely there's a conspiracy for Ishgard to slaughter its own manpower in a time of a shortage of manpower, and the Dravanians are not the wounded whiter then white puppies some seem to promote them as.
They do slaughter entire villages with women and children and don't have any consideration to the targets they actually go after. (They attack the adventurers enough.)
