Just because I love this thread and I am 55 and it doesnt seem to go higher than that.
Howling Stones 54+ Should be able to ride this out to 58-60 though the smart move is to go to Chardok for AOE whenever you can if your goal is to get to 60 asap
Read this thread, mainly the post by Tecmos (check out his videos too)

I did entrance yesterday and it was hard scary and fun. I agroed the east pather by sending in a pet to attack who took a weird path along the the platform
Also another note about CoM. at 54/55 I have started grabbing any cleric in the zone that is 39+ and just keeping a pet and letting them CH once in a while. I can keep the whole 2nd floor clear and I take ~80% cut of the exp and the Cleric is still doing more than a yellow per hour. Its a fair trade off and works out really nicely.
