The implication of the belfs in the new story is terrible. Lor'themar is turned into a scumbag idiot who will stand by and allow the Sunreavers to get butchered upholding the laws of the Horde and of the Warchief back to back with the same person who ... butchered Sunreavers not so long ago.
The Belfs were ready to join the Alliance in MoP and I totally get that since the other option was to be killed off one by one just cause Garrosh didn't like them, so I can't blame Lor'themar for seeking other options. But then the purge of Dalaran happens which enrages the belfs. So they would rather go back to being killed off one by one instead of being killed all at once.
Now we get this abomination of a story that makes no goddamn sense. First of all, why the hell would he be the one turning against Sylvanas who, for better or worse only helped him and his people out when they were in need, that is to say, during the same time the Alliance was sabotaging the belf efforts to reclaim their lands. She supports them in retaking their home and vouches for them to join the Horde.
There's also that bit with the blackmail (which wasn't really blackmail) and that turned out well for them. So I see absolutely no reason they would hold it against Sylvanas. So for better or worse, Sylvanas helped them more than anyone around them. The Forsaken did for them what they did for the Nightborne.
But ok, being a scumbag is sometimes a thing. However making deals with Jaina Proudmoore of all people? Come on! They could have, at least used a different character and even then it wouldn't have made much sense but it does not shamelessly take a proverbial shit on the previously established story. It would have made more sense if Varian was the one alive pushing the truce and Jaina would be dead.
What the hell is this?
