60 Rogue: 20/31/0 - WoW 1.11

I just did the math in an excel file, and found that Dragon's Call deals a bit more DPS then Dal'Rend's Sacred Charge over 10 Minutes using nothing but Sinister Strike and constant Regular Attacks. Here are the calculations I came up with. PLEASE tell me if I messed up anywhere, or compare/contrast why Dal'Rend's Sacred Charge maybe better then Dragon's Call.

Sorry if this is a newbie question/calculation post. =(

Dragon's Call in Main Hand http://www.thottbot.com/?i=21782
One-Hand Sword
72 - 135 Damage Speed 2.50
(41.4 damage per second)
Durability 105 / 105
Requires Level 52
Chance on hit: Calls forth an Emerald Dragon Whelp to protect you in battle for a short period of time.
Calculations:
Fight Time = 10 Minutes = 600 Seconds = 6000 Energy = 150 Sinister Strikes
Regular Attacks = 600/2.5 = 240
Sinister Strike Attacks = 600 Seconds * 20 Energy/Second = 6000 Energy / 40 Energy/Sinister Strike = 150 Sinister Strikes
Total Number of Attacks = 240 + 150 = 390
Regular Damage = (72+135)/2 = 103.5 Damage Per Attack * 240 Attacks = 24840 Damage
Sinister Strike Damage = 103.5 + 72.5 = 176 Damage Per Attack * 150 Attacks = 26400 Damage
Welp Summoned = 390 Attacks /100%*6% Proc Rate = 23.4 Procs, so 23
Welp Damage = 23 Summons * 250 Damage Per Welp Attack * 3 Welp Attacks = 17250 Damage
Total Damage Output over 10 Minutes = 24840+26400+17250= 68490 Damage
Total DPS over 10 Minutes = (24840+26400+17250) Damage / 600 Seconds = 114.2 DPS

Dal'Rend's Sacred Charge in Main Hand http://www.thottbot.com/?i=23785
Main Hand Sword
81 - 151 Damage Speed 2.80
(41.4 damage per second)
+4 Strength
Durability 90 / 90
Requires Level 58
Equip: Improves your chance to get a critical strike by 1%.
Calculations:
Fight Time = 10 Minutes = 600 Seconds = 6000 Energy = 150 Sinister Strikes
Regular Attacks = 600/2.8 = 214
Crit Attacks = 214/100*1 = 2
Total Regular Attacks with Crit Rate Added = 216
Sinister Strike Attacks = 600 Seconds * 20 Energy/Second = 6000 Energy / 40 Energy/Sinister Strike = 150 Sinister Strikes
Crit Attacks = 150/100*1 = 1.5, so 1
Sinister Strike Attacks with Crit Rate Added = 151
Total Number of Attacks = 216+151 = 367
Regular Damage = (81+151)/2 = 116 Damage Per Attack * 216 Attacks = 25056 Damage
Sinister Strike Damage = 116 + 72.5 = 188.5 Damage Per Attack * 151 Attacks = 28463 Damage
Total Damage Output over 10 Minutes = 25056+28463 = 53519 Damage
Total DPS Over 10 Minutes = (25056+28463) Damage / 600 Seconds = 89.2 DPS

Conclusion:
68490 Damage vs 53519 Damage
114.2 DPS vs 89.2 DPS
Dragon's Call > Dal'Rend's Sacred Charge

Synposis: Your post! =)

I now realize how stupid this post is. If an admin could delete this post, my stupidity maybe hidden for another day!

An epic is better than a blue 6 levels higher than it. Stop the presses!
