You just need to play around with the class a lil more. I'm currently lvl 30 right now and am usually at the top or near it in war zones concerning damage and kills. A lot of people are unhappy with the class because it takes a lil bit more to master than others. If you want a class that puts out good damage with lil effort, then ya you probably need to re-roll. But marauders are fine, you just have to be willing to work for it.

Might as well say my piece also since I'm sitting here waiting in a queue to get on my server. Currently lvl 30 marauder and loving it as well. It is def a very situational type of play and can understand why so many people are unhappy with it, but in my opinion if your willing to put in the effort it is a very rewarding class. 1v1 I win at least 80% of the time, if someone is healing me I feel unstoppable and proceed to cut down one after the other. I can see peoples opinion that other classes can do the same or more damage more efficiently, but it just feels more rewarding to me when I get me wins off my marauder. Then again, as I feel I am mastering the class more and more, I'm often topping DPS and total damage in war zones, and at the very least in the top three. It is a difficult class, but not underpowered....at least that's just my opinion.
