Fair enough. I still think it's a copout that the official reason they're oblivious to the rest of the world is that no one outside thought of making contact with the last standing Highborne civilization for 10 000 years. I mean, was AU-Gul'dan really the only one capable of communicating with them through the shield?
Not that the lore inconsistencies really bother me, I've been having a great time with Legion these past weeks.
I agree to a degree. Big events (e.g. death of a major character) should happen in game. And as Case Vol'jin showed, if you're going to develop a character with the intention of getting people to like him, it's better to have his finest moments in the game and not some book a small portion of the playerbase would read. I think they did well with Elisande though, especially since the comic is free and accessible online.
