What I think happened...
It was probably around the first content patch into MoP. It was a job well done (despite the whining the release content was well-made), most of the content was mostly done and they were working on WoD. Pretty sure Hearthstone was just ramping up and Heroes of the Storm was fleshing out enough to be ready for a closed beta. So they take some people from the WoW team, add to and make teams for those games (I'm sure hearthstone started out with two people, a team wasn't in place yet). It came slowly to the realization the deadlines were screwed up. WoD work slowed down as they focused on MoP patches, and it wasn't until the last patch did they realize WoD wouldn't be ready. And even by then more people were taken to work on Legion, and while they did hire more people they weren't yet brought up to speed. So that took time and even then some of those new people went immediately to Legion. So Warlords was behind in a very bad way, which is why the last MoP content patch went on as long as it did.
And even in that time it was obvious Warlords had to be rushed. They made a new 2-patch/yearly expansion model and they were already behind. So Warlords was chosen to bite the bullet while more resources were devoted to Legion. You can see some evidence most of the levelling content was already done as well as the cinematics, but end-game took the axe. They scaled the XP to speed up the 90 - 100 level process and threw into end-game, cutting and piecing together a concise enough story. The big plot points were intact, but they had to cut some of the in-between material. And Taanan jungle was locked out and saved for later. 6.0 and 6.1 and the small patched in between were poorly executed as they had no time and no resources and they cobbled what they could together.
The plan was made with Warlords to take the fall to "rebound" back with Legion which they were putting more resources into, and be a more full expansion overall. The problem was the Burning Legion. Again. To be fair my gripe ISN'T just the Legion, but the SAME Legion plot. They're taking over again, they found another way in, onos... There's naga, you could have redone those Cata water zones and expanded them as you were banking on before. There's an old god still under Tirfisal Glade, You could do Nerubian as a vast underground area. You can recycle those assets and still make a decent story. Hell how much material in assets were thrown together over the years that didn't make the cut for expansions? You could have recycled that for less and it would be new to us. You didn't have to do TBC2.
I won't argue Legion will be good, great, awesome of a steaming pile but I just can't bring myself to feel like I WANT to experience that. They are throwing the Vrykul back from Wrath, they are bring Dalaran to the new continent, they are bringing back Illidan, they are also doing much fan service like Alleria and the Emerland Nightmare just feels like they are just trying to cater to old lore simply because they could be out of newer ideas.
And let's be honest PvPers got jack shit for Warlords. They got re-skinned gear, no new modes nor battlegrounds.
