RAP is not everything to hunters these days. With extended fights, and bosses that hit like f*cking trucks, you need more than just high RAP.
Kazmo (just using as an example, no harm meant) has some impressive RAP. However, his HP and MP are, dare I say, pathetic. I have nearly 2k more of each than he, and only slightly less RAP. He may put out some large numbers early on, but I'll outlast him every fight, every time, and have a higher damage output total.
Further more, he's sacrificed crit chance. I have over 2% more than he.
Now, I'm not saying he's a bad hunter, probably far from it, but in either PvP or PvE, the lack of other stats is going to hurt him in the long run.
Just something to keep in mind.
