E More class-specific gear: yes. Mandatory and time gated? Probably not. In one of the interviews, Yoshi explained that you can get gear from the new crafting tokens and this was an alternative to our current hardcore melding system, which will still be there and will be the fastest way to gear. I feel pretty confident stating the token gear will be class specific. The melded gear: I don't know if they will go specific or all classes.
Edit: I would be fine with class specific because I really enjoyed every class looking unique (Lord knows they didn't play unique so the look sure was nice). Even though I have the full Artisan set, I actually kept my AF crafter gear and still use it as my normal stuff unless I am doing 4*.
