Will the usual mats still be usable?

Still wrapping my head around the new system, but Loriri's guide is pretty spot on. Basically, a lot of mats are going to be obsolete. Some will convert into tokens which will open a shop to purchase new mats.

I'm planning an informational TERA stream on this once we're closer to the update. I'll have one of our localization team members on the air and we'll explain the new system in its entirety.
