@ Augustus b'Raass: Not to worry mate: Just a turn of phrase (it exists both in English and in German, although I don't know which colour signifies envy in the Hive Slums of Amsterdam .
The latest models are excellent, and I am really happy that you've put the banner to good use! Maybe you should consider experimenting with the pose of the head on the banner bearer, though: At the moment, it looks as though he's looking upwards in adoration -- not neccessarily a bad effect for an icon bearer, to be sure, but a true berzerker should maybe be looking along his bolt pistol's barrel instead?
A2! Wow. I only use A4 (good though eh).
Now you really have a flair for World Eaters. Think you need at least another two, or ten. And a Lord to go with them. Transport maybe too.
Don't worry: I've already put a devious plan in motion that should compel Augustus to give us yet more World Eaters -- let's call it the old tactical bitz drop assault, shall we?
