I was thinking about how BFA could end and there's this one idea that resonated in my mind for a while now.
Inspired by the loading screen of BfA, the Sylvanas meleeing Anduin 1v1, also the fact that Sylvanas WANTS to invade Stormwind, she feels like it's the only step for her.
The raid would be marginally different for both Alliance and Horde, I loved how Siege of Orgrimmar was kinda different for each factions, but I feel like it can be dragged a little more, to tell a story from two points of view at once. Stormwind is a beautiful location and it would be treat using some of those city places as raid boss arenas.
The general premise of the raid's faction duality is Horde is invading through harbor while Alliance is defending. The Horde raid instance starts on a forsaken galeon ship that just beached on the docks and fights it's way through the city all the way up to throne room. The Alliance raid instance starts in throne room and gradually pushes the attackers back to bay until a final confrontation on the forsaken flagship.
What? players will face different bosses ? how's that balanced. How about just same mechanics on different models.
Horde
The horde starts on board of Sylvanas's personal ship. Sylvanas sends Baine and Lor'themar, while herself stays on the ship to command the battle. The first boss encounter would be the dock's defender. The first mighty warrior that defends the stormwind. ( I am thinking the mounted general Hammond Clay or Halfus Wyrmbane, or someone of that calliber). After defeating this foe and scalling it's way up the harbor stairs into the city, Lor'Themar sees the city already partly on fire, destroyed full of rubble and hard to navigate. He decides that the only way to the throne room is through the underground canal system. Here comes the second encounter, a giant Crocolisk living in the sewers who's blocking the way. When the canals join up to the stormwind stockades, you fight the third encounter, the Stockades Riot. I imagine this fight alongside of Spoils of Pandaria, where you slowly open up jails and fight the fugitives and prison guards. After emerging from the stockades on the opposite part of the city, right before the stormwind keep court, you are encountered by Jaina Proudmoore, who conjures a giant water elemental from the fountain that's infront of the keep. When defeated, she would faint from the magical power she just expelled and the horde forces would capture her (this is to get her out of the battle without having to kill her of) This would be an excelent boss + boss arena. When you finally breach the keep, you are stopped by Genn Greymane who you need to defeat to lay foot in the throne room. In the throne room awaits the last boss, which is Alleria Windrunner. The stormwind throne room would make for an awesome boss arena.
Alliance
The alliance starts in the throne room with Anduin, first boss encounter would be an Assasin, that sneaked it's way through the brawl in the streets to take out the king directly. After you take him down, you march down the keep to the streets. Here you find the city in total turmoil. Barricaded, on fire, under fire, destroyed. Kinda like the map navigates in old Stratholme, you go through the various streets until Anduin decides that the only way through this rubble would be through the underground canal system. This would stretch out the map of the raid beyond just what you normally see in Stormwind. In the canals, there would be a second boss, a giant Crocolisk blocking the way. After the canals join into stormwind stockades, there's third encounter, the Stockades Riot. I imagined this one as Spoils of Pandaria encounter. You slowly open up cages and fight the fugitives (those would be Horde PoW and various prominent mobs we encountered and defeated on Kul'Tiras and Zandalar). After emerging from the stockades on the other side of the town, the only way to the docks is through the Lion's Rest and that's where you encounter the Lor'Themar's blood elven army. The next boss is giant Anima/Blood golem. After this combat the Alliance defenders capture Baine Bloodhoof, who gets wounded in this battle (it's to get him out of the picture without killing him of). In the harbor, the elite forsaken forces won't let you anyway near the ships until you deal with their commander Nathanos Blightcaller. The last boss would be Sylvanas Windrunner herself, on top of her flagship galeon. The ship needs to mirror the Stormwind throne room, as so the boss arenas were the same. But this could be done with a HUGE ship that has a circular platform on one side.
Now, ever since I'v visited Nexus on Heroic and fought a faction specific boss I fell in love with this idea. Of one raid, but two reasons to fight for each faction.
The first boss would be An Orc Assasin for Alliance and Human Warrior Defender for Horde, second and third bosses would be shared, a giant Crocolisk and Prison Riot, the fourth boss would be Giant blood golem for Alliance and Jaina's surpreme elemental for Horde. Fifth would be Genn Greymane for Horde and Nathanos Blightcaller for Alliance. I think these characters in particular are very simillar in their roles. They would make for an excelet mirror fight. Nathanos could send waves of plaguehounds, while Greymane would send waves of worgens.
The last boss I feel would be best represented by the Windrunner sisters. Both extremely deadly with their dark powers, and both very similar.
Yes, Alliance would get a much better ending in this one. Horde gets to kill a really minor character, while Alliance kills the one of the most popular characters in wow.
BUT, Anduin cannot die. It's cannon, he lives to be old. Also, the Windrunner sisters make for one hell of a mirror fight.
The ending cinematic for Horde would be Lor'Themar pinning Alleria with arrow and then stabbing her through the stomach as he rumbles something about traitors and stuff. While Alleria sends regards to Sylvanas and tells him that she will be waiting for her in hell.
The ending cinematic for Alliance would be simply Anduin stabbing Sylvanas through the stomach and then having some heroic babble. I don't care about this.
So what do you think? Before you decide to type "wow, what a shit idea, glad you're not a blizzard writer", I would much rather apreciate if you'd just offer an alternative instead.
