I am having some issues pulling above the 2k mark in heroics. I am using the standard rotation rend, MS, overpower and execute. slam when all else is on cool down. I do know my gear is not the best but i think i should be able to pull more then 2k dps. Any advise on enchants, gear, spec or geming would be appreciated.
You need to get hit capped and expertise capped. Hit cap is 264 and expertise is 26. Without being capped your are missing your targets. Your enchanting and gemming will evolve around these stats at first, then go all strength. Strength is key. Other stats like crit will come naturally from better gear. The darkmoon card of berserker is for pvp. Anything resilience oriented is for pvp. Maxdps.com will clue you in on gear choices for arms warriors. A site like WoW Heroes - World of Warcraft PvE character info & ratings will help with what enchants are best.
