Data-slates is perfect. And yes, under AoS rules they're so easy to resolve. I've come to hate templates so much.
@ magenb
Agreed. I prefer AoSs living rule book system.
@ GML
I could do with less ambiguity in the rules too.
One thing I'd keep is the is the current system for casting physic powers. Just roll a dice for each warp charge needed. On a 4+ it's harnessed. Double 6s are still perils of the warp. Powers can be simplified, like AoS's arcane bolt and mystic shield.
