I'll try to keep this short and to the point.
If i were playing Black Templars, I would have to take target priority tests because the codex overrides the rulebook, correct?
And if i were playing Tau, my Kroot units could see through intervening forest for the purpose of line of sight, correct?
In both cases, a codex rule references something no longer in the main rulebook, however, the way i've always seen people play it is that the Templars MUST take a target priority test, while the Kroot's rule does not apply.
Am I wrong, or are these two scenarios wrong?
