While I certainly hate to play 'Devil's Advocate' for any improvements anyone wants, the problem with HELM is definitely mostly the distance between points. Harvesting Grauberg, for example, is only slightly annoying to me. People HELM to get things they need, the solution might actually be to make points more abundant/differently spaced and nothing more. The issue of the value of HELM results or the overlap with other places that drop a few of the items is harder to fix and less of an issue. We HELM because we need something and tend to get something else.

Other people don't HELM because it's frustrating because the points are too far apart and they don't profit.

The result is that when you have something rare you need from HELM, something that is probably only rare because the design is one where SOMEONE should be out there doing the gathering almost 100% of the time, we can't get it, because no one is doing HELM so the 'random' lucky hits from them aren't showing up on AH, so we have to go ourselves, but it's too rare for an hour of HELM by one person to matter.

If HELM were overall less annoying, more people would do it, more people would hit the lucky rare items more often and sell them, and everything would overall 'work', but then 'RMT could do it'. I don't think that's an argument though because RMT can do anything. There's nothing simplistic that you can make 'annoying to RMT' that won't end up annoying legit players who want to relax and do it. HELM is simplistic.
