I just completed the Main Story yesterday, and after a day of celebrating by running around Ul'dah like a tool in my AF, spamming Scorn, I'm ready to get serious and start the next phase.

I know I need DL to go on after this point, and I need Tomes to do that, but here's the problem. I hate being a burden. It comes from my years in the service I guess, I hate to be the weak link in the chain, I literally feel guilt over it. So I wanted to know the best place to start farming AToP and Myth if possible, without being a drag on the group. I am a Lv50 Paladin, full AF1, full HQ amber accessories, a high dungeon shield (don't remember which but its higher then the HQ stuff on the AH), and will have a Flame Lieutenant's Katzbalger by Monday (I can't play on the weekends because I work).

So with that, where should I start? And what are the best guides for said place?

Thanks
