The recent news of the Titan's being overzealous slave owners is interesting at best. Given the information that the water of the titans enslaves dragons and is therefore just as bad as the Old God's corruption , I think the true meaning of the expansion Dragonflight is misinterpreted.
I believe the true "Dragonflight" of the expansion is the five flights gaining independence from the titans, ie the 'flight' meaning 'fleeing'.
