surprisingly, slam DPS is better with faster weapons. Which is another reason why a 31/30 build does slightly more personal dps than a 33/28 build does. But the 2 points for blood frenzy usually out weight the difference by increasing overall raid dps a bit.
I'd go with the gladiator's greatsword, given the 2 things your doing. Specifically, your gimping your personal PvE DPS by going 2h and blood frenzy, is 8-10 dps gonna really deflate your raids overall raid DPS that much, probably not. But you still want to do PvP, and the S1 sword is way better for PvP than the Khorium Champion is.
