I'm not a huge lore buff, I haven't read any of the books or gotten too deep into hidden/less known stuff, but I still play the games and follow the general story arcs. I'd like to know though, besides Garrosh escaping, what did our entire time on Pandaria actually add to the game story-wise?
- Vanilla: Leading into LK, some continuation from WC3 Human/Undead Campaigns
- BC: Start of Legion stuff and (at the time) wrap-up from WC3, such as Illidan/Maiev (Night Elf Campaign)
- LK: Continuation of Vanilla and wrap-up from WC3 Human/Undead Campaigns
- Cataclysm: New threat that when defeated ended the Age of Chaos on Azeroth and leading into the Age of Mortals. (bit weak here too but there was a decent conclusion. Also the whole world tearing was pretty neat in concept and story-wise)
- MoP: Uh... Pandaria-exclusive stuff that hasn't been known prior or even touched since, Y'Shaarj (who we still know fuck-all about) and Garrosh, Garrosh escapes (this could have happened literally anywhere but proves how incompetent Pandaren prisons are), dies pretty much immediately in the expansion (you didn't even hit level 100 before he got wrecked by Thrall), and leads into WoD
- WoD: Continuation from MoP shenanigans, we put an end to the AU Iron Horde but AU Gul'dan and Archimonde do their shit, leading to...
- Legion: Demon-invaded Broken Isles and the second huge demon invasion.
