OK.. I have a peeve...
If you see a LFM with either In Progress or Make your own way, Don't join unless you can actually get there by yourself. Seriously.
If you see me posting this, realize that I will not come and get you, show you where the quest is and basically hold your hand.
I'm already tired of teaching (like 6 months ago), and if you're joining my party and you're not ready and capable... please realize that the odds of me coming out (and thusly slowing the instance's progress) for you is very unlikely.
Now, I'm not saying that a noob can't join, just be ready. Have your own healing covered. Carry the pots you'll need and think you'll need and be prepared to run fast... the odds that the path is clear is pretty good, and the quest odds are is almost done... so don't be afraid to join.. just be ready & self sufficient.
So far I've met few new people who understand what they're getting into...
thus the post.
