The time argument is always awful. You're essentially saying the content is badly designed. Because content that is so not engaging that you just want to have the least amount of time possible dedicated to it, is objectively bad content.
You think adds/trash are boring -> Combat of the game is badly designed. Good designed combat doesn't rely almost entirely on specific boss fights to be fun.
You think dungeons are just a chore players shouldn't spend more time on -> Dungeon design is terrible. Good dungeon design makes you not feel like you're "wasting time" by playing through it.

Maybe it's time to admit most of you think the pve content in the game outside the high-end raids is poorly designed.
