Fight duration also comes into play but i think the data was more for disproving the "ZOMG parry haste is the worst part of DW" fallicy. Myth busted.
As much as Toth is a great addition to the frost tree, i am interested in seeing back to back base avoidance and survivability stat comparison between dw frost and 2h. considering the point i saw someone made earlier about 6 extra talent points (minimum 3 for toth + gl getting ur hit high enough without speccing into the other dw talent) and issues with maintaining crit cap without ssg. there are a lot of variables involved and alot of rng that can swing one way or another during an encounter, so base stats would probably be a more reliable glimpse at the difference between the two.
If i were to bet one way or the other, i'd bet it on 2h'er.
not because of ssg or "parry haste" mythology more down to the fact that the extra hit and talent points required are pulling from other areas of our tree or stats that could be used for extra survivability.
