Classic Is the main Dragonflight campaign still required?

Interested in returning to try the new patch. Twice before, I leveled to max with friends via casual dungeon grinding and was then gated from various aspects of the game due to my status with the campaign. Can it be bypassed in any way at this point in the expansion, or are you still required to complete it on at least one character? via /r/wow https://ift.tt/wr9lWJy
