I had a titan barb with a polearm that also did a huge amount of damage
Probably not that far behind blessed hammer damage. I could probably do the math to find out just how far behind...if I can remember the gear I was using.
*edit*
I just did some serious thinking and this is the damage with the gear I remember having (can't remember the magical charms I had, I do remember having perfect attributes anni & torch) :
Minimum whirlwind damage : 6168.6
Maximum whirlwind damage : 17030.7
Chance of crushing blow (25% hp damage to non boss/player targets) : 25%
Chance of double damage (deadly strike "combined" with critical strike) : 59.44%
Whirlwind speed : 4 fpa (6.2 attacks per second)
So an average damage of 11599.65 is good enough to compete with a lot of the starting hammerdin in terms of damage but obviously hammer damage could go a lot higher if you don't include that I'm doing double that damage at least half the time.
This of course is something not to try on hardcore (unless you're rich & have lots of time) because it's a barb with every stat dumped into strength, damage was calculated with a lvl90 char in mind because I think I stopped it at 90.
Personally I'll miss this very option...to go full strength! and my smiter
