I am trying to learn this new codex right now. I am not liking how Reavers turned out... they were one of my favourites, and are still possibly my favourite model. But now.. I dunno.
When I charge with them, if the target unit is in difficult terrain, does this mean they are automatically having to make dangerous terrain tests? I cannot see anything to contradict this, but perhaps I am missing something. If so, I don't think I will ever spend points on them. Or if I do, it will be expressly to go tank hunting.
