I ve been playing warcraft for 1,5 years..Havent tried warrior yet but my boyfriend had one as his main and some of my friends do too..
tanks are essential for groups,so a tank will always find a slot for a dungeon/instance/raid..Dps usually cant.Because lots of warcrafters plays as a dps.
(I m a hunter btw,a dps..so I know)
that site has example talent tree builds and tips and good addons.
you can try allakhazam.com too(if I misspelled google it)
btw if u enjoy dps,u may try mage(very high dps) or hunter (goes a long way with arrows) too..
or shaman could be a nice choice..
hope u like wow and welcome to the azeroth =)
If you happen to come to nagrand server,you may whisper my hunter "Afush"
