I've read a number of forum threads discussing whether a model gets 'look out sir' against a vindicare assassin's 'deadshot' special rule, and the overwhelming consensus seems to be yes, which is a decision I'm perfectly happy to go along with, because in exchange he get's to pop land raiders even more often e.t.c. But in a game I played recently my opponent argued that he should get
LoS against my vindicare (fine) but also that his focused witchfire ignored
LoS (It was the awesome head-explodey one). Whilst both of these make perfect sense from a fluff perspective (how would your comrade protect you from a nasty case of exploding head?

) the wording for 'deadshot' seems very similar to the wording for focused witchfire. Is there anywhere where this is explicitly cleared up?
Thanks in advance!
