CS / HotR can resolve to a miss, dodge, or parry and those combat table resolutions are reduced by both hit and expertise (expertise is equal up to hardcap because the amt of parry per point after 7.5% is identical to dodge per pt below 7.5%)
Judgment can resolve to a miss and is only affected by physical hit
Grand Crusader is granted on-cast, so the resolution of the Avenger's is irrelevant, it's merely that the frequency of proc is proportional to CS hitting (which is physical hit and expertise).
In general, expertise is less valuable than hit below cap because it does not affect Judgment. Expertise contributes the same to CS and the GC proc frequency all the way to parry hardcap.
