there is already a "mythic" weekly dungeon coming out... why not just take hold of m+ completely. Adding another end game aspect would be a great time filler.
Also a chance for cosmetic perks!! (Mounts, xmog scrolls, titles, etc)
This would take away the (down-time between raid tiers.) Gives people a chance to push dungeons and could ultimately shake up the loot table for raiding when dungeon trinkets all of the sudden are close to raid ilvl.
M+ allows smaller groups of friends to also gain a loot quality of raiding, and is still extremely challenging.. (sky is the limit on key difficulty).
2. -Death running-
Running back to instance could be updated to current expansions. (At least lower level dungeons when the run can literally be 5 minutes back to the dungeons.) Wiping and spawning at the dungeon entrance is purely a quality of life. (Zero skill in running back to raids...) we already get to rebuff everyone, that is enough of a "lesson" for wiping.
3. -Cross-faction gameplay-
We are playing an xpac that is over a decade old. If we want to kill the other faction.... let em run free in battlegrounds. This would massively improve que times for random dungeons, increase raid group quantity, and allow more people to play together in general.

More applicable to 15-70 dungeons and raids. Running to Uldaman, Maraudon, Sunken Temple, Blackrock Spire and Depths, Molten Core, Blackwing Lair, Gnomeregan, and some other instance entrances from nearest spirit healer is the most frustrating mood killer. It's clear they gave more thought to it when WotLK was in development, and that streamlining could be introduced to old content as QoL update.
Could be tested on Frostmourne S3, and see how it would change things, if at all. If it's deemed good QoL update, Warmane could consider making the change to Lordaeron and Icecrown as well in the future.
I like spirit walks. They give you more time to think what went wrong and people in LFD groups can chat more during them. Usually during the dungeon people just stay quiet because they cant slack.
