I like the idea of them, but I don't think it was executed well. I would like the rewards to scale with the number of players. I'm already finding it difficult to pug for a group outside of daily reset time. I've been in a couple of groups now that just start as soon as we are able to (5 players) because we have already waited for too long. Additionally, due to using the public system as opposed to the LFG tool, we must physically wait inside the instance instead of just setting up an LFG and doing other things while waiting for it to fill. Because of this, sometimes I really struggle to hit all 3 daily chests even though I am an experienced raider and know I am doing loads of DPS. Feels bad when you are carrying a group and fail to hit all the chests simply due to not having enough players. This doesn't promote players to try to improve or run more optimized builds in preparation for raids, it's just another "more players = win" typical in PvE.
