Knowbie Stuck on progression . Help is appreciated (5,1K gs) . <3

Hallo Night Elf Warrior Tank with 5,1k gs (Icecrown Wotlk) ! Am stuck and i dont know what to do . In most raids they ask for 5,5k gs tanks and i dont know how to get better gear to reach 5,5k . Do i just farm every day 2 frost Empblems to get the better gear ? That is too slow .
My Rep is ---
Argent Crus. =Exolted
KirinTor =Exalted
Knights of the ebon blade= Honored
The Wyrmrest Acoord =Friendly

Explorers League = Friendly
The Frost born = Friendly
The silver covenant = friendly
Valiance Expedition = Honored

Yes. Do VoA10/25 for a chance at your t10 legs/gloves. Run Rep farms for your ring. Do daily RDFHC. Keep your eyes open for "gearing runs". They are normally 5k+ and do 4-6 bosses on average. It's not a "problem" you're having, that's the nature of the "grind". You can't pick the game up today and have a fully decked out character in a few weeks unless you have a guild/friends to literally feed you items or you donate for the gear.
