I've been looking around on here a lot and seen several different types of rogue builds. Out of the ones I've seen, I think I like the 13 rogue/6 ranger/1 something builds the most, though I suppose there's definitely something to be said for the ridiculous number of skills you can have with a 19 rogue/1 something build.
My question is, are all the extra skills worth giving up 10% attack speed and the free dual wield feats you get by going ranger? Also I've seen a lot of people mention acrobat as the prestige class to go with in the the 13/6/1 build - is that accurate?
