I don't really pay attention unless it's a special attacks, those stick out since they're in yellow. A lot of the off-hand crits do about the same damage as a regular main-hand hit, so those aren't really noticeable. Also, as a rogue, the numbers continuously roll off the head fairly rapidly, and you don't have time to pay attention to some of them. If say, I Sinister Strike, both weapon attacks off at same time, and get a sword-spec proc off at the same time, I think only 3 numbers show, so sometimes you don't even see all the numbers.

Either way, he should crit a few times per mob. And the fact that you don't have time to look at any of the numbers is buns, unless you're in first person looking behind yourself *all* the time.

So this baby seal walks into a club.
