Well geeze guys you jump down a newbs throat for making some assumptions before asking but you let Pers recommend Nightblade and don't give him a full page of thread back talk??? He's at least been around for awhile and knows better.
Now Zshadow, when you say you saw a "twink" "going damn good" with those weapons you were in an XP match wheren't you? Because
purple + minor enchants anything = damn good in an xp match.
So, what you would like to know is why your choices were so horrible right? OKay, dual wield is for fury warriors and fury warriors at 39 don't get crap for abilities to use in fury. So basically what you would be doing is, whirlwinding for 1 second and then getting your butt kicked for 9 seconds before you can whirlwind again.
Now compare this to Overpower that you get in Arms (which by the way, completely sucks with 1h) or Revenge in defensive. Not to mention Rend in both stances.(also super dependent on melee weapon dmg)
To conclude a DW arms spec is a horrible idea, a DW fury spec is a horrible idea, a DW prot warrior is a horrible idea (but here's a horrible spec to go with it XD
dual wield prot warrior rawrzors )
If you attempt to try any of the three we will laugh at you till our sides hurt (i'll still give you props for trying the DW prot warrior spec cause I'm weird like that).
Powerglove made a nice walk-through for arms warriors in the guide section and I made one for prot.
If you don't have access to heirloom items you might want to check out my guide for a wider list of weapons and armor and work with what you can get your hands on.
PEACE!
