If you keep dying, standard or warbands obviously, you can stay at the same level and farm currency over and over in that zone. This is a big deal with the new card farming nerf which will help to get more of them. If you are unfamiliar, each two levels you are higher than the zone decreases your drop-rate.
So just make a lvl 60something, and have him farm docks over and over while dying to get a better chance at the jack-in-the-box divination cards.
I've logged some decent time since the start of the game and never thought about this. Hopefully it helps someone else!
