Let's see what happens when we compare the dps of a human twf tempest ranger, with a human thf frenzied beserker. I'm using human because it is a good average baseline race, and because I can compare the two styles independent of racial enhancements/abilities (not gonna count HV boosts). I'm also only going to compare only what each class/style brings to the table, so no external buffs, class specific raid loot, pots, or item clickies. Just the spells/enhancements/abilities that come with the build.
Assumptions: Min2 khopesh or Great Axe vs acid immune mob, + 6 stat items, bloodstone, 18 base Str, +2tomes, max damage related enhancements.

total THF dps = 185.4
Hopefully my calculations are correct.
p.s. The interesting thing I see is how much higher dps goes when all external factors are considered (buffs, songs, clickies, extra gear effects, etc). When people post 300+dps numbers, fully 1/2 to 1/3 of their dps comes from factors unrelated to the build. Are there truly gimped builds, or is it mostly just a lack of the right buffs and farmed gear? Makes me wonder just how far can you buff up and gear out a "gimped" build? Can you actually make it respectable with enough buff, fluff, and stuff?
