gw gold will take advantage for you, when you are first time to use warrior. A warrior as a secondary profession, some may say that it is a complete waste as a secondary profession, but it can be used very nicly in conjunction with other professions. I will give my experience on using warrior as a secondary profession, I hope you will like it.
My first and most used character is a ranger/warrior, and it has some definite advantages. Sprint is a must have to get to the best possible locations in your environment, and Frenzy definitely works well with a ranger (it allows your attacks to be 33% faster at the expense of double damage), seeing as they are not a usual target. The skill Endure Pain is an advantage to have in any class. It increases your health and armor enough that it can make a huge difference in any battle.
Elementalist - The ability to use fire skills that burn your opponent, such as Mark of Rodgort can work very effectively with the Warrior. Combine it with skills like flurry and some high damaging sword skills, you will be able to dish out some major damage. And what better than to use Elementalist skills when you have the benefit of being able to use Energy Storage as your primary
attribute, which increases your energy each time you raise it.
Ranger - An effective combination, you can combine the Ranger expertise with warrior hammer skills, which a lot of them are energy based. You can effectively spam their hammer skills for low energy cost while still retaining a high DPS and good enough armor to still be considered a tank.
