I saw Overlord Theophany post this in "The Rogue Compendium [updated 10/26/08]"
***************************************************
# 5/51/5 (Combat fist/dagger)
If your raid doesn't have an arms warrior or another combat rogue, this is what you should be speccing…
# 51/5/5 (Mutilate)
The only other PvE build. This is a higher personal DPS build than combat, but if your raid does not have an arms warrior or combat rogue, you should be combat…
***************************************************
My spec is the 5/51/5 my armory is:
http://www.wowarmory.com/character-sheet.xml?r=Alterac+Mountains&n=Yuckfoo
I use WP/WP on both daggers while doing our heroic runs. Thankfully my 5-man team is geared way better than I am but I am still pulling 1k.
5-man team setup: Prot Warrior, Boomkin, Mage (switches specs), Survival hunter, and myself.
Now with that being said I know combat is best if you don't have an arms spec warrior in a raid, but since heroic's are 5-man would the more DPS from the mutilate spec be better or should I stick with combat for the Relentless Strikes?
For raids I am the only combat rogue and until we get another or an arms warrior in 10-mans I'll stick with combat, just am not sure if it is worth it in 5-mans.
Any suggestions are greatly appreciated.
