Other than just hypothetical situation, why would you run VoG gear? The Arms give increased super energy on Oracle or Praetorian Kill but I find there just aren't enough of either to justify that bonus. Especially as a Titan when Ruin Wings are an option. The Legs from both raids are identical in heavy weapon ammo bonus, so nothing special there. The Chest Piece has no raid-oriented bonuses. The Helmet is really the only one that has a bonus that actually works throughout the whole raid, But my Hunter's going to use Achlyophage Symbiote and I'm quite keen on Apotheosis Veil and Obsidian Mind for my Warlock- depending on which class I'm running.
