Well, despite the fact his English is pretty bad, allow me to offer some advice.
Most HNM shells will not tolerate you missing out on camping to do other things in game. If you're somewhere else in the game and obviously not AFK, chances are, you will end up being kicked out. You have to be willing to drop what you're doing to camp.
Secondly, most reputable HNM LS's don't recruit, you have to go to them. Find out who the good HNM LS's are on your server, go to their websites, and apply. A decent LS with a good leader won't respond to your 2 sentence post.
If you don't want to use your RDM, then leave it out of the application. But I'm warning you, this will hinder you more. DDs are a dime a dozen, and most decent HNM LS's require you to have 1 mage job and 1 melee job. The only exception I've seen is if you're strictly a mage with multiple useful mage jobs.
But the most important thing is the first thing I brought up. If you're completely unwilling to drop what you're doing in game to help camp, then no reputable LS is going to accept you. I suggest you re-evaluate what you really want to do in game and with who.
