so when i started the xpac my choco was at rank 6. seems like i really dont get the oppurtunity to pull him out all that much. id like to do some grinding with him. where in HW is a good place to grind out some exp at lvl 55 and below? or should i wait till 60?

only reason i ask is because i have to grind out 1.7m exp to get to level 56 and will continue to grind out exp each level because i am not doing side quests. so that leaves me with hunts, fates and dungeons.
