Just trying out two classes without giving all three a go and maxing them out won't give you the full perspective. Each class is catered to a different kind of play style. Apparently the hunter just isn't for you, which might blow in your opinion but it's just that you can't play with and enjoy that class. (There's no such thing as a best class btw as everything gets freaking wrecked in any game mode by someone or something stronger or better than you in some way)
