First bring back the kill X boss in X raid quest we had in legion to help get gear.
2nd use the time walking feature to create a queueable raid instance for the sole purpose of killing one single boss per week to be rewarded with an item from the normal raid of the current raid tier.
Example: Quest is to kill Razorscale, the queue would fill the raid as per normal (or you can do it manually) you join the raid AT the boss NO TRASH! kill the boss collect your weekly reward.
it’s a small 5-15min thing that would be a nice change of scenery especially for catch up gear, as it’s only normal mode loot it’s not required for the sweats just breathing a bit of life into casual content we have lost over the years.
This would be available every week (different boss/raid each week)
