Oh yeah, we're playing orcs and we've just stormed a citadel, so they're in hallways and bows aren't very accessible here. Plus, when I've been doing Sacrifice Attack, it's usually been when they can't hit me (i.e. they're engaged with another player), so I do a Deliberate, Flank max Sacrifice Attack, and I'm killing elves left and right.
His DB is in the 70s (Magic Shield, Magic Armor, the adjustments from AbtP, Shield Training, etc), so he actually has a little bit of DB left over when he does his attack, but still, each attack has been very pretty good, but adding +50 to my crit roll is /almost/ a guarenteed kill!
