I'm a level 20 night elf warrior and i've been plaything the game for 3 days or so. Is there any good shoulder armors or any type of armor thats good for a lvl 20 warrior? thanks.
when i mean by any type of armor it means chest, legs, gauntlets, boots, etc.
and i meant shoulder not should. sorry for the typo.

You should que up for dungeons using the dungeon finder tool at the bottom of your screen. Dungeons drop some of the best armour which can be used at your specific lvl. Depending on if your dps or a tank it will determine how long the wait is for obtaining a dungeon group and entering a dungeon. Although the wait may be long at times once you enter the dungeon you will be rewarded. During these long dungeon waits you can quest at specific areas. Id check out the alliance quest board. Dungeons you may enter can be wailing caverns and others. Also quests give great armour at your lvl but none is equal to that armour which may be obtained from dungeons. BTW check out world of warcrafts website and you can get better answers off the forums
