So I assume some of you have seen these new rules that have been leaked.
To sum up the Wave Serpent's shield has been nerfed to one use only and 24 inch range.
Otherwise it appears that EVERY single unit in the book has been buffed dramatically. Multiple units have had their firepower drastically improved or the durability. All Distort weapons are now Strength D.
The word on the street is there are no points changes significant enough to compensate for these changes. A guy on Warseer has taken a picture of the book in his hands so the rumors are now fact.
