Hey there,
I can definitely agree that the Dunes and Quifim can be extremely frustrating. My solution has been to either give advice to someone that is new, or not doing their job effectively or "correctly". If that doesn't work and they refuse the advice, or if someone is being rude - I leave.
In leveling my pld, you wouldn't believe the knuckleheads i've run into that are pulling with voke. When I've tried to explain that it is not a very good tactic for the party situation I'm usually met with either some rude smartass remark, or that they don't have a ranged (it's usually the smartass remark). So, I can either deal with it, or leave. It's that easy.
I've also taken several days off from lvling in these places to do farming, missions/quests with ls, or wait until a ls member or friend wants to go together to make a pt. I'll go back to it after I've cooled off a bit.
It does seem like a crap shoot though. However, I'm more than willing to give advice or help another player out as long as they are willing to accept it. After all, we were all new at one point, and I certainly don't know all there is to know so I still rely on others for help to.
Sorry that you aren't on my server. I'd pt with you ^^!
Good luck!
