People in pugs are gonna look for 5k+, and since you can hit that by only running heroics, feel free to farm up your gear. Their also going to laugh at you for wearing blues, so even though those pieces are not weak, their color makes them so. They also probably look at your health and gemming. Re-gem everything but your helm with 30 stamina, regardless of whether or not you are replacing the piece soon. Regem your helm with 10 dodge or agi and 15 stamina. Enchant your gear; 225 armor on cloak, 40 stam on bracer, 30 stam/15 resil on shoulder, 18 stam or 240 armor on gloves, and max out your professions to get the maximum you can out of them.
