Yeah its a pun.
So basically, there was this show years back called LOST, im sure many will recognize it. Its opening several episodes were cool to watch and follow building of its setting/plots, but after some time with nothing really getting explained or unraveling and instead even more plots and twists I totally lost interest and stopped giving a ... care. It was a mess.
What this does have to do with WoW you ask? Well, I got a flashbacks of it following WoW lore for some time. Namely end of WoD. It feels like people responsible for WoW's lore at some point just panicked that they are running of of plots and started to mass produce them. For some ~5years no story came to definitive end. There's sooo many open plots, and nothing seems to be ending anytime soon. I mean, some stories need a good build up and more than 2 dimensions but everything seems to be very blurred at this point.
Even recent cinematic with Sylvanas where she stated "No more secrets, no more lies"... then proceeds to trashtalk without explaining ANYTHING. I mean if she tries to get Anduin on her side, a simple explanation of her plan and point of view could be more than enough, provided its reasonable.
