Thanks again for the input, all -- I suppose that if I do use the DF I ought to just make clear it is not a speed run and if they don't like it then it just isn't going to work and I'll leave so they can get someone faster. My WP times are usually around 25-30 mins, given good dps, and shorter if I get in groups with relic/+1 people. Like I mentioned, my groups are always far enough ahead of the wanderers to not get caught, so that isn't really an issue. I think the general consensus should be as others have stated here -- if it is DF, don't ever expect a speed run of any sort and don't be disappointed when you don't get one.

I also think I am too used to the dps mentality (having waited hours on my bard for runs) and never think that the group actually needs me when I'm tanking >.> <.<
