Warhammer 40k is an every changing game. The last six months has been a roller coaster of a ride the likes we have never seen. So many codex releases and a new edition to absorb means what was once good is no longer the cat's meow. Today's face of 40k is no longer the super human Space Marines. Heck today's face is not even human! The last 2 alien codexes has changed what everyone is playing or has changed what people are preparing to face.
