Less of an expansion but a trilogy of expabsions because id like to see an over arching story told
Pick a theme or two: xp 1 is rebirth, xp 2 balance is needed, birth of a titan
Pick a cast of Main characters: velan, the naru, the aspects, thrall, anduin, azeroth, the void lords, magni.
Pick a cast of secondary characters, and tell their stories: this is hard because i want to say a new world with new races, a world that was under attack by the legion when sargeras was defeated for the rebirth xp, for balance is needed focusing on yrel and the army of light, alleria and her husband, then the remenants of the mag’har and the furthering alliance of the belfs and nightborne. Xp 3 would really like tonsee jasper gallywix get stomped for being stupid and greedy
Pick an established (or new) place on Azeroth to visit/revist: xp1, a new world with maybe 4 to 6 major races, architecture of maybe south east asia/india, go back to argus as well and maradum. Xp 3 further explore the worlds from the first xp with a huge focus on argus.
Adding this:
The story: this is assuming the dragonflights get their powers back and tyr copy paste survives. Valen gets a vision of a world in distress. Half corrupted with a noble spirit still fighting but they are losing, he is able to convince the leaders at a meeting with the aspects and tyr that they should send people to investigate because he worries it deals with the legion. Players are sent as scouts, and we can see what has happened to the legion since sargeras was defeated, we help the native races fight back and eventually get the legion invasion slightly contained but realize that half the world has become a demon world so they can resurrect quickly there, players report it to the council and eventually its decided that there might be a way to cleanse the world of the taint much like the titans did to azeroth. The would be x.0 to x.2.5 for the expansion, x.3 and x.3.5 would introduce yrels army of the light investigating it(not yrel herself but a high ranking general) they try to convince people to join them leadership refuses and valen is killed in the final cutscene either via assassination or sacrifice to let azeroth know whats coming
2nd xp horde and alliance sign a defensive pact knowing whats coming, scarlet brotherhood finds out about the army of light through a spy and sabatoge defenses and try to convert people scaring the masses, yrel and the AoL arrive in the eastern kingdoms sieging stormwind, gilneas, ironforge and silvermoon. Nightborne and the remnants of the forsaken break the siege of silvermoon(players lead the forsaken andnightborne in a dungeon), the horde decide that a new warchief must be named until the threat is defeated(similar to dictators pre caeser era rome) the choice is Zekhan, during this time yrel tries to recruit the lightbound. Alleria speaks against it but a naru does naru stuff claiming she like azeroth is void tainted and must be purged turaylon is compelled to kill her and just as he is about to kill her anduin arrives tries to convince him not to but is blasted out of the castle in stormwind by a naru(preferably this is a dungeon with the players escorting anduin) as the cutscene ends you hear the sound of a swlrd slicing through the air and allerias last scream. One of zekhans generals apologizes and mentions now would be the perfect time to end the alliance, Zekhans struggles for a moment as Telajedi watches on as he eventually says “do what must be done”. End of base game raid is ironforge is about to fall everything is going wrong the players are fighting trying to clear it and keep leadership alive with anduin, just as they are about to be overwhelmed goblin airships crest the horrizon flanked by zandalari trolls on ptryerdactls who crash into the rear of the AoL killing the general who had valen killed. 1.0 to 2.0 the aspects are targetted for assassination. 2.0 to 3.0 Army of Light attempt to kill the world soul, also during the .1 patch(i did not play shadowlands so this might not work but) those who die to the army of light are offered a chance to be reborn as forsaken thus allowing new forsaken races. As all looks lost the allies from the previous xp arrives and help defeat the death of the world soul, but the battle has caused azeroth to start being born.
Xp 3, what happens when a titan is born? Does it shatter the planet? Does it change the ecosytems? Potentially everyone must flee to outlands or argus/new world from xp 1 zekhan becomes what garrosh could have been per the maghar recruitment. The greatest war chief of the horde and alliance.
