Really not a fan of this move. I got that many people were tired of "pure good golden boy" portrayal of Anduin, but starting with the very MoP there was more or less clear NATURAL build up to "will he or wont he" fate of Anduin, with his Shadow and Light powers.
Thats why that sudden poke to undeath feels like an extremely anticlimactic way to speed up his development. It feels FORCED and ARTIFICIAL.
Same comes to Arthas 2.0 parallels. There were some across last few expansions but NONE of them played out naturally.
Arthas had strong portrayal, went through slow development and was built up to be a Lich King through numerous tragic events and decisions.
Anduin was literally yeeted by flying girls, caged and then poked with the sword to undeath. Voila, he is a bad guy now.
And you are already know what is going to happen - he will be freed from mind control and feel bad for what he has done. But in fact nothing would be different from how he was before SL. Same golden boy, but with an edgy look.
Very cheap and very lazy writing. I really hope people wont eat it up, its almost as bad as Sylvanas stuff story and character wise.
