After I saw the 64 class spreadsheet for the first time some months ago I dug a bit deeper to find any information about which role I would prefer to play. After some research I found out that it is NOT 64 unique classes that I thought it would be, nor was it a talent system that would make it close enough either.
There will be 8 classes. The 64 variations will address some minor changes to the class but it won't be a new set of class abilities unique for the role you choose.

If you choose to be a Guardian (Tank/Tank), you are a tank. If you choose Knight (Tank/Fighter) you are still a tank, not DPS as far as I have understood it.

I think Intrepid need to focus on clarify this more since it starts to become an real issue. Many people still think it is 64 unique classes even tho Steven has said it won't be in a few interviews and on the Q&A. I see a lot of comments that people are daydreaming on what unique class to choose. Even streamers are making content on what they think the different class combo's will be like. Remove the 64 class spreadsheet since it only confuses those who don't follow the game updates closely.
This is something that might kill the hype train or cast doubts on the project.

While we don't have any plans to adjust the terminology for your 8 archetypes leading to 64 classes at this time, we'll be sharing more info on what those unique augments would provide as we lead up to future testing, to give you a better idea of what to expect in terms of variety on that front <3

I think Jeff's description in the recent live stream shared above may help clarify that a bit further as well, in terms of setting expectations - though he does tweak the phrasing a bit 😄
