I agree with removing the book name from the feats. As is noted here updated feats overrule earlier versions.
When I added the complete warrior data I tagged the name CWar as a reminder of the source. However since more custom data has been added then duplicates have been uncovered.
I think the replace Id mechanism is the best method to deal with older duplication, Users that don't have both sources flagged would only see the newer data.

On a side note ETA on the MIC - Specific Weapons data, Friday 25th February. All weapons from Magic item compendium have been entered only the relic weapons need to be fully coded. I'm grinding through the deities and the respective abilities.
Hopefully it should be in the 1.4 release.
