I'm looking at Word of the Emperor, for example, or similar powers, that work based on Leadership tests.
WotE basically says "A unit needs to pass an Ld test to assault the psyker/unit using this power." Well, does a fearless unit ignore that? the Fearless USR points out Morale and Pinning tests, but not necessarily Leadership tests.
I personally think that leadership tests, morale tests and pinning tests are all separate things, even if they're all based on the Leadership statistic.
So any clarification on this issue would be appreciated!
