Balmung is a actually extremely easy to get into the "Bounty Hunters" LS (The one you're referring to), however the issue is most people just /sh and expect an instant-LS invite.

use this link to find the leaders of Bounty Hunters and send them a tell. It's a little more work but honestly, I have never been unable to get in when I wanted to be in Bounty Hunters. Though this might be a more recent symptom with so many people at 60 that it gets full again, this was a problem back when they first started. However, since they constantly remove people, it shouldn't be.
Post-Edit in, and additional Thoughts:
I do want to add, I think that the hunting community is extremely disgusting at times. There are multiple issues that I take note of:
People will blame people for "early pulling" and will complain loudly in chat. However, I have been in zone when the initial shout went up, and they waited 3-4 minutes. That is more than enough time to get to just about anywhere in this game, even with load times, unless we're talking instanced content.
I find these people who yell about early pulls to be far more toxic than anyone else. The people who they oft accuse of "Early pulling" don't even respond, meanwhile I've seen these self-same people calling those who 'pulled early' some of the most disgusting words I have ever seen. To those of you that think that "Early Pullers" are toxic, please keep yourself in check in this regard - as I find it absolutely disgusting the way you treat people you don't know just because you missed a fight.
I also find the Witchhunting within LS's to be outright rediculous. I know that the Leaders of Boutny Hunters have an entire LS for their leaders which is basically a witchhunting LS. I know that people will shout names using <tt> macro's to try and call out people who "Pulled early", often blaming high-threat classes such as Warriors for a pull just because they know how to pull threat.
I have seen people who, just by spreading a rumor, will get blamed for early pulling When they are not even in the same zone as the hunt mob. It is outright rediculous just how far players go to try and point their finger and cry "Unfair" without showing an ounce of concern for their fellow humans.
You guys want Hunts to be better? Stop complaining in shout. Stop hunting your fellow hunters and focus on the mobs. If you find yourself struggling to get to a hunt target, then just relax and go do something else. There is plenty of content in the game right now that you don't require to spam hunts.
