All the races, except the Blood Elves, have Warriors in their ranks.
does has a few abilities that restore hitpoints and otherwise some bandages can be used which isn't that time-taking either.
The Warriors have the Protection talent tree if they want to become good tanks. In this talent tree there are a lot of abilities that reduce the damage done to the Warrior. You will also improve your threat done with this talent tree and will gain some new nice abilities like Spell Reflection, Shield Slam, Shock Wave and Last Stand. A Warrior can be a great tank, in my opinion, Blizzard designed Warriors to be tanks and they are the best at it.
Since WoTLK, the Arms tree is considered to be the weakest talent tree by many Warriors. This is basically because the Fury talent tree has received some great talents that make the Fury talent tree just as good or maybe even better for PvP and it stayed better in PvE. The Arms tree was good because of the Mortal Strike's debuff left on the character that reduced healing done on him by 50%. Now the Fury Warriors have something similar in the talent tree called Furious Attacks which also gives the same debuff of 50% healing reduced on the target. If you follow this tree you will be able to Dual Wield two two-handed weapons as only class in WoW! It doesn't only look great but boosts the damage as well and puts the Arms build even more in the shadows. Then there is Heroic Fury, another PvP talent that removes immobilizing effects and removes the cooldown from your intercept.
