I did all that during a similar content drought (13 months of SoO in Pandaria) and just had to do the new stuff in Legion and that is already done:

I even killed the rare mobs that drop loot that will be turned into toys with the next xpac.
So the only content I can do is to try kill Archimonde Mythic (we are 9/13 right now) and PVP. I really dislike PVP (and still try it from time to time just to get reminded how much I dislike it), so there is really not much to do for someone who never dropped the ball in the game and continued to sub and play.
