I just don’t want to have to listen to my mercenary firing off joss whedon style marvel movie quips, like I know blizz loves to do. I cannot stand it, I don’t want to listen to it. I don’t want to “get to know” my mercenary. Your writing and voice acting are bad, and forcing us to experience more of it will make mercs annoying.
edit: In addition to that, the idea of a merc kind of takes away from certain build fantasies, like if having a druid werewolf pack ever becomes a thing. A werewolf druid running around with 6 other werewolves…oh and btw here’s this idiot spouting annoying marvel movie quips off to the side just following us around.
