It feels wrong how lazy Blizzard is making a MOP Remix using the incomplete mess that the this expansion is currently in Retail due to multiple story content that was removed.
There is no way to play the full story in Retail and there will be no way to it in the Remix due to all the story chapters that has been removed.
Orgrimmar and Stormwind: Those cities should have the MOP version of the city, without anocronisms. That means to have Garrosh and Varian. Other city leaders from the MOP era should be in their respective cities too. For Garrosh they could make it so players once start the Siege of Orgrimmar raid change to not seen Garrosh anymore.
Valley of the Four Winds: It is so crucial to MOP story the original valley. It makes no sense to have a MOP Remix with the Valley already corrupted, specially when it has been partially restored in Retail (but without the original story). It should have the original Valley and then have Zidormi to portal to the corrupted Valley, maybe requiring players to be max level to unlock it.
Patch 5.3 The Barrens Story: Not having this content makes the story makes a jump between the Throne of Thunder and Siege of Orgrimmar.
Legendary Cloack Quest chain: This chain is crucial for the expansion story. It was wrong that the quest chain was removed at the end of MOP and it is wrong that this isn’t restored for the Remix. Even if the chain is too much grind they can change it to reduce some quests in the chain, for example requiring completing every raid once instead of farming multiple quest items in multiple runs of the raids.
Brawler’s Guild: Maybe this is not essential for the story but it was a nice side story. Given the Guild hasn’t returned since the end of BFA this would be a great occasion to have it back.
Challenge Mode: It is true that this has nothing to do with the story but CM was the precursor of currenly Mythic+ so it will be nice to have it back for the Remix.
About the rewards and prestige: Before you jump complaining that all of this should be exclusve for people who do it keep in mind I am not asking for any of the rewards to return. I am asking for the content. I believe a good compromise could be to restore all this content with new rewards. Make new achievements for doing those things with a Timerunner character and give new rewards. For example the Challenge Mode recolors could be a valid reward for doing CM in the Remix. Or just put Bronze coins as rewards.
I know people who did it back them don’t want the rewards to return, but I also did it back them and I want to do those things again. I want to do Challenge Modes again. I want to replay the removed quest chains again. I want to fight in the Brawler’s Guild again. I want to return to the original Valley. I want to make a new character and play all MOP story again from the start up to the end on Siege of Orgrimmar, without missing any chapter.
