You've seen this guy before. Hes one of the most famous

infomercial hosts in television history (although this guy is gaining fast). His name is Chef Tony, and he sells the Ultimate Chopper.

ZOMGWTFBBQ am I talking about? STFU, k?1! YOU, silly rogue. Ask yourself, how often do you use slice and dice? Yeah, yeah, I know. Even a noob rogue knows this should be one of his or her most oft used abilities. But do you really, I mean

*really,*know how important it is to your overall dps output? Take a look at these, a very simple set of calculations to understand the mechanics of the skill.

First, your overall dps is determined by a combination of your main hand damage and your off hand damage. Take a look at the damage tooltip for your melee stats. In my case, 349.5 damage per second. In other words, if I began attacking a "paper-doll" without using any specials, over the course of 1 minute I should do 20,970 points of damage. Right? Well, not really. Rogues do miss quite a bit, and our targets often dodge our attacks...and then there are glancing blows. But then, hmmm...what about my 23.38% chance to crit? And uh, well...ok I lied. It's not really all that accurate to combine both the dps ratings for each hand into one. There are entirely too many circumstantial modifiers for me to try and make a realistic calculation. But the numbers look pretty, so why not just for arguments sake?

OK, so, back to that 349.5 number. Simple enough, 201.2 + 148.3. Any idea how much of an increase slice and dice adds? Well, itd be better to think of slice and dice as addition by subtraction. That is, from your attack speed. By 30%. My main hand dagger goes from 1.80 to 1.38, my off hand from 1.50 to 1.15. Here comes the fun stuff.

In order to figure the damage per second of either main or offhand, you first need to take the average between their respective minimum and maximum (which is affected by attack power and stuff, I just dont feel like looking it up).

Main Hand = ([394 + 330]/2)/1.80, or, 201.1, uh, 201.2 (no idea why the tooltip doesn't match).

Off Hand = ([241 + 204]/2)/1.50, or, 148.3.

201.2 + 148.3 = 349.5

At rank 2, Slice and Dice reduces attack speed by 30%.

1.80/(1+0.3) = 1.38.

1.50 /(1+0.3) = 1.15.

Now...

Main Hand = ([394 + 330]/2)/1.38, or, 262.3.

Off Hand = ([241 + 204]/2)/1.15, or, 193.4.

262.3 + 193.9 = 455.7.

455.7 - 349.5 = 106.2

What does this all mean? I am gimping myself one hundred six and two-tenths (106.2) points of damage for every second that I do not have Slice and Dice up.

Over one minute? 6,372.

Remeber 20,970? Try 27,342.

Now, do this using your own numbers, and ask yourself, "Do I pay enough attention to Slice and Dice?".

Dislcaimer: Due to the author's mathematical ignorance, the above calculations are subject to be completely wrong. Well, this came true, as GSH kindly pointed out. I adjusted my terrible calculations and viola...I fail.
