I wonder if we will get to use some of the WoD's special abilities from the trailer? Like the one where their Conjurer enchanted the Ranger's arrow with fire energy (1.0 CNJ used to have access to all 6 elemental magicks, including En-spells, like Enfire).

I also wonder if Vrtra/Azdaja fled from, or were captured and brought to The First, by Allagans. Given there are Dragons on the First and Midgardsrmr, the father of all Dragons came to the Source after the 13 shards split.
