Weapons and classFollow

Just a quick question which i'm sure has been asked before, but how does the weapon skill system work in WoW. Is it like FFXI whrere each class is better in one specific type of weapon or can any class be just as good as another class with a weapon as long as they have been trained in it and have maxed out skill. Basicly i would like my Druid to use one handed axe's (mainly for off hand item bonuses) and was wandering if i would be only able to obtain a lesser weapon skill compared to my staff. Any answers would be most helpful, thanks.
