I personally plan on using a combination of the different gear, but the themes would be VoG on my Titan, PoE on my warlock, and have my hunter be ToO...how about you?
Edit #1: someone posted a poll like this before me, sorry for the repetitiveness.
Edit #2: Will you have a different setup in PVE than PVP? I personally wear PVP gear based on stats and care less about the looks.
