When I first found out the IA romance was a "Joiner" I wasn't too thrilled. Not a fan of bugs, insects, whatever. But I decided to give Vec a chance and get to know the character. He's effective DPS although a lot more squishy than some of the other companions. Since I'm an Operative-healer though we make a good team, him tearing them down and me doing the support. His banters get kind of annoying, but after listening to Theran's "I'm a pacifist" comments and Corso's good ole' boy's "yeeehaw's" for hours of play time, pretty much I can ignore anything. As to the character himself, give him a chance and get to know him. The Vector romance is my favorite in the game because he is so sweet and supportive of the IA lady, and displays a remarkable vulnerability in some of his later scenes. He's used to having the support of the entire hive but his feelings for his lady are new territory for them, they can't help him with her,and he's going into scary 'feelings' territory blind. I realize different strokes for different folks, if you don't like the character not much is going to make him appealing to you, but I don't see him that way at all. He's not my favorite character in the game, but he is my favorite romance.
