A good defensive warrior
At the beginning of your leveling up, it may have some trouble. Each class has low hp, low defense, bad weapon and bad armor at start. Players can hardly complete the quests. Star Wars Galaxies credits are often killed by mobs. As a Warrior, you will have better weapons and armors when you reach level 22, while other classes have AOE. From that time onwards, leveling up a warrior is really slow. You will feel bored if you are not a patient person. You may accomplish a quest in one hour, and those AOE classes could finish this in 15 minutes. Solo a quest offers them more experience points and saves their time. Nevertheless, warriors have heavy armors. It is a good idea to accept any party invitation from other AOE classes. You can be the shield and castle wall. In this period, you find some many advantages of being a defensive warrior. Your teammates need a good defensive warrior a lot. Usually, you have to solo the quests. Since two handed weapons could do much more damage, it is smart to become a Berserker. You will have stronger attack. That would be very useful for soloing.
