The secondary archetype will change the character's class & role WAY more than most people are anticipating.
Many people on these forums have taken the position that the Secondary choice will only add minor modifications, or "flavor", to your primary archetype abilities. However, Steven is on record as saying it can
dramatically change your character's
role and your active abilities.

Balancing 64 unique classes would be near impossible, but IS has made it clear that they are not looking to balance all of the classes.
I am anticipating 64 fairly unique classes. I mean, do people really think that Ashes will only have 1 healer, with 8 slightly different variations? No. There will be multiple unique healers (not including the Bard, tbd on that). My only hope is that there aren't a small handful of clear metas (High Priest, Guardian, etc).
I am further predicting that the 64 classes will end up being one of the most beloved features of Ashes.
Mark it.
