Why do people dislike him?

He didn't drop everything and rush straight to Terra like a normal person would have.

Worse, he's vanilla in a franchise known for its excitingly bizarre flavours. 40k is dumb as fuck and doesn't need some cunt trying to be sensible about things.

Success breeds jealousy

He's a retard. Fuck him

Im not knocking it aside from the fact we could instead be following the guys who are all about 3D popout books, or goosebump adventure books. Instead however we keep getting the stock standard books we all know are just average.

Juxtaposition. If everyone's special, no one is. You need a sensible (for the setting) core that makes all the weirdos even weirder. The pink haired girl with the nose ring stands out when she's not in a crowd of rainbow hair and piercings.

Is everything you do in life the most interesting thing? How boring does that get, when you have to constantly think of new ways to do things as not to fall into mediocrity?

They used to when Matt Ward was writing him.

Now he's eh pretty cool guy.

Yeah its much better instead to just be boring the whole time so as not to ever get sick of doing exciting things and having to come up with new ideas.

Go away Lorgar.
You were a loser pre-heresy and you're an even bigger loser now
