Hello there!
Mages are very powerful characters and very usefull endgame,
Talents:
Fire – Single target dps, Good for raiding and killing bosses (Leveling 2)
Frost – Multi Target dps, Lots of area damage and good for leveling, the best to level with.
Arcane – Single and multi target arena and battleground pvp, Poor for leveling and raiding, but good to use in pvp

SImply the spells in the book arn’t powerful enough and you will find leveling a bit more tricky, the best thing to do is follow a leveling build, click the link below to choose one. And then Click button “N” when ingame (if you have a level 9) From there click on the same as the build.

P.S Need anymore help? ask!

you always learn all the spells in the book going a fire mage means that your fire spells will be more improved and that you will learn new abilities within the fire tree it doesnt mean that you only learn fire spells
