Read the thread. Seriously. It's your job to learn to play, not ours to teach you.
I would appreciate some dps advice, as I just do not see what I'm doing wrong. I keep reading about hunters putting up 6k dps and looking at posts showing 6.7k dps potential in the spreadsheet, but I can't seem to break 5k myself.
I run a 1/18/52 SV build which seems pretty standard. I have glyphs for Serpent Sting, Steady Shot, and Aspect of the Hawk. I use Mammoth Cutters for ammo on all boss fights, along with Flask of Endless Rage and either 80 atk pwr food or 40 crit rating food.
My shot rotation includes keeping Serpent Sting on the target at all times, then Explosive shot -> Steady Shot until L&L procs at which point I alternate Explosive and Arcane. I've tried also weaving in Multi-shot but I did not see much of an increase and mana became an issue. I also do not do the trap dancing, but try to stay at Sniper Training distance.
I use a cat for a pet with the standard spec with the exception that I got HotP instead of CotW.
