Dailies and rares. These things are not fun at all because there are no stakes. At least in the maw you were sort of time capped so there was an aspect of strategy(you didn't have the option to simply waste your day doing every possible thing).
This kind of content needs to be given an alternative. I want the chance to defeat a difficult opponent or do a time limit quest. I want a chance at more than what the easy slow content gives at the cost of possibly failing and getting much less than what the slow content gives. The fact that the game has no-stakes chores is always the fundamental thing that puts me off and makes me stop playing because thats not a real video game and i know it and i feel like an idiot for "playing" it.
Blizzard wonder's why they don't get respect. It's because they disrespect a huge part of the player base every time they log in wanting to play a video game and are instead given chores.
