Outside of raiding, pvp and m+ gear feels almost useless. Alts are almost dead. When you are done with "main character activities" there is literally no point to gear up your alt. WHY WOULD YOU?
There is no real need for gear to casuals. Why would you need a better gear? Legion raids are mostly overtuned and getting from 200 to 226 def vont help you that much.
World quests? Who the F*** even doing them? They are completely pointles. No 450+ mounts achievement, no cool rewards for casuals to achieve.
Whats the point of getting stronger outside of pve progression for most players?
