Illidan and Black Temple was the end of a long military campaign which had the "forces of good" go from eliminating Illidan's source of new forces (killing mag and ending fel orcs), stopping him from controlling the water supply of an entire world (Coilfang), and then stopping what seemed to be Kael aiding him sucking the mana (life?) from outland. We find out later that killing Kael really just stopped him from leading a crusade against Illidan which would have resulted in a civil war that ripped outland apart. Then we kill Kael and TBC is over lore-wise.Originally Posted by petninja
KJ pops up and corrupts some people, but the sunwell storyline is as flimsy as it gets. Not to mention he appears 1 year (real time) afterward (we can assume 5 + years in loretime right?). The horde would have shrunk back to its 3 race core, the nelfs would have been reaching out to the belfs (possibly alienating the humans), the forsaken are still not a legit race, and draeni would have skipped town and tried to resettle and rebuild outlands.
Possibly a new alliance would form, but we are talking about a single battle that is fought, and it would MAYBE be reforged along the same lines (in reality the Belfs are begging everyone for help, draeni are benevolently helping everyone, the main horde/alliance factions ignore each other and save the world, while the forsaken sit this one out.
Wrath is the second great military campaign of wrath (although really its not nearly as focused...) in any case, in all likelyhood this is many years later and we have a slight reshuffling of alliances ala WWI to WWII.
