I would not recommend going just one type of class. Because the game throws different type of enemies at you sometimes rangers or mages and if your a pure warrior you will never get close because they keep hitting you and will probably kill you before you get close. Especially if there is 5 of them and only one of you. Pure mage is bad because you have a cool down for you spells and in the middle of a battle 5 seconds or 10 can be the difference between life and death. Don't forget if a melee enemy gets close your done for. Me im going ranger with a little warrior, no warrior skills but i have a sword and sheild for when i do close combat and it works fine. Right now it seems all i fight is ranged people.
