they may have removed AP, but there are still plenty of grinds.
soulbinds will be a long grind, especially if you want to max them all out. (guessing itll take 1 month to max 1 soulbind, so thats the entire patch sorted if there are 5-6)
legendaries will be a grind. (probably several weeks per legendary, depending on how much of that tower you do. guesing you will have to tryhard to get one by raid release.)
the new weekly chest seems to reward playing more. (you will want to have a box with lots of choice for the first month orso of a patch)
and that's before cosmetics.
