XvermonX, your post is enlightening, but the way you've stated several things are inaccurate (you're not wrong in your understanding, just how you posted it).

That's only for the offhand weapon. Your main weapon hits just as often as ever, so going from 1H to Dual Wielded 1H is going to be an improvement in overall damage - and quite probably a significant one.
Second, your calculation:
Quote:
(main dps) + (off hand/2) * 0.25 = over all dps
The way you wrote it is wrong. Wielding two 1H weapons that are 10 DPS, using that formula, would result in a DPS of 3.75 - and I'm sure we can all agree
that's not right. The proper way to write it would be:
Main DPS = X
Offhand DPS = Y
X + ((Y/2) * .25) = overall DPS
Or, in the principle of KISS:
X + (Y/8) = overall DPS
But that's not even the accurate formula, anyway. You've reduced accuracy to 25%, not 75%. The real formula is:
X + ((Y/2) * .75) - overall DPS
In our previous example of two 10 DPS weapons, the end result is 13.75 DPS - much closer to that 15 DPS hypothetical 2H weapon. And the Dual Wielded 1H weapons may be a better choice after all, since attacking more often gives more chances for critical hits and wreaks havoc with enemy spellcasting.
