But you can destroy such block easier. Shoot it or assault it and it goes away. Not so with fearless formations. And even if withdraw rules were changed, they would still not apply to fearless formations as they can stay put or remain closer than others ...
Seem like you are irritated about it. Well, I am irritated about tyranids quite much. 
So if you are ready to make tyranids less irritating, I am ready to see your pain with fearless marines. Before that should we settle about that that it is part of them and we have to live with it.

@Tiny-Tim: If you are going to make non-fearless unit to Slaanesh-list, then make sure it is not confused with Emperors Children, which are fearless, every one of them. Before GW publishes something about True Original Kult Legions, I keep teachings of my old Codex: Chaos Marines true, and it says that every EC has Mark Of Slaanesh and in that book it is same as fearless. New Codex is about Renegades and Black Legion and nothing it says is about Original Kult Traitors.
