First off, here's my armory: http://us.battle.net/wow/en/characte...t%C3%AB/simple
1. Is Insignia of the Corrupted Mind RF version better than VPLC Normal?
2. Is Rathrak Normal and 378 OH better than 378 version of legendary staff?
3. Would it be better to use the 3 pc 384 t13 gear I have over the 378 4 pc I currently have? (I don't have access to 4 pc yet)
