It’s good to have another perspective! As my tags said, I’ll probably read it when it comes out in trade, so I can have the whole story arc in one. (This is why I’m not a huge comics reader, and when I do read comics, it’s in trade – I like judging bigger story arcs, not small pieces at a time.)
I don’t have trouble believing that Vex was a different person at the beginning of Vox Machina than she was when we finally saw her on-stream, but some of the panels/details I’ve seen of her in the comic on Twitter/Tumblr make me wary. But I suppose I’ll see for myself when I do eventually read the whole thing.
There’s being a different person and there’s turning her into a greedy bitch who embraces her elven heritage, talks shit about her mother, and generally only seems to exist to be the meaner twin and a foil for Vax as the desginated protagonist. Also graduating from an assassin school your diplomat father yent you to at age 14. That’s just dainty. I will believe in a lot of character development, but this Vex goes against basically everything the character and her arc were about. Also, taking the cast saying they love it all as proof that everyone loves everything is a little… Well. Of course they’re not going to publically disparage a well-selling product of their brand.
