Having badass ranged weaponry and being a good shot are two different things, and I don't think BS 4 for one unit in the whole army makes us spoiled. Fluff wise it made sense. Hive guard were genetically engineered to be ranged fire support that could triangulate positions by seeing through the eyes of the rest of the swarm, and they had guns that fired bullets they could direct and aim with their minds.
I get that, but Arnt the fire caste bred form birth for combat, even before that?
And their guns I believe have an AI to aid aiming, their data net work works just like the hive mind...
And it's like saying, why can't assault marines be WS5? It's only 1 unit! Or something like that...
I'm not being rude, I just think that you don't need bs 4, you already ignore cover saves, surely that's worth a bs to be able to bend it like beckam?
Through temptation and horror
I have held to my faith
As a drowning man grasps at a rock
Judge me not by my weakness
Remember not my sins of late
