Well, StD are supposed to be that heavy armored forces.
If i like bunch of naked guys i play Khorne, if i want strong magic, i play Tzeench. So yes, people want to play warriors, knights and chariots.
It's like telling a Tzeench player, your army is stronger without magic and treachery and if you don't like it play another army.
This is you guys only and ever repeating argument. Go play another army.
But you know what? People play the warriors since 10+ years and don't want to play another army, they want their gaming experience, they had since forever.
So please spare me this, go play another army. If i want to ignore facts and look away if something is wrong, i would join a church.
But i want to play warhammer like i used to the last 10+ years. And yes, this book sucks epic, doesn't matter how you look at it.
