Well just to clear things up for you:
70 and 79 bracket are two different things
The 70 bracket includes levels 70-74.
The 79 bracket includes level 75-79.
There is absolutely zero activity in the 75-79 bracket, and if interested in a higher level toon, redirect yourself to the 80s forum thread.
Hunters are one of the least desired classes in the 70 bracket (forgive me meat). They require a good healer to do most everything, because, like most other classes, rogues will tear you up. You want to roll Nelf for racial, you will need to use that and feign death perfectly to stay alive. Resilience won't help you much, you will drop fast either way. Stack straight agility and go to work. Try not to queue without a pocket healer, as you will get lol'd on by most classes in open combat (ie. WSG).
