Trolling: The act of posting with intent to obtain a significant negative reaction from the board members by bringing up a subject that is predujicial or offensive to their members.
Now, in this case, you feel you are asking a legitimate question. We do get quite a few trolls around here though so a question like yours tends to be taken as a troll question.
Hunters should NOT be singled out as having a 'bad reputation', at least no more so than any other class. A Huntard is just someone who is clueless on how to play the class or someone who intentionally missplays it for purposes of 'fun'. Generally, we don't include Role-Player hunters in this category as they could be following whatever character motives drive their play.
Hunters HAVE the 'bad reptuation' because as has been said, it is a popular class for newer players due to the "Legolas" effect but unless you count Gimli (in Peter Jackson's version of LotR) as his 'pet' then I don't really see it beyond having a ranged weapon. So while there is probably a higher percentage of hunters being played, the percentage of the clueless playing them is probably about the same as any other class. I can't say this for a fact because nobody has done a statistical analisys that I am aware of...
So, while your question is simple, it is answered in full in the "Every question answered here" sticky that is at the top of the forum. Take a browse through it, and when you have questions after reading that, you'll probably find the crowd around here a bit less trigger happy on the troll response... ^_^
