On this character I had to go into my primary epic destiny and into full tank mode, but this is EE and I have no problem with that.
As a tank the damage from most mobs was noticeable and I had to keep an eye on my health, using Lay On Hands, Pots and cocoon I was able to keep my character up long enough to kill 100 plus mobs.
The human melee mobs seemed to hit my character a bit to often in comparison to the other mobs. I was hit 3 out 5 or 2 out of 3 swings each doing 100 HP damage, which in dealing with mobs in 1 and 2s was okay but 4 melee mobs at once spelt trouble.
The quest was slow because I was pulling mobs in 2 and 3s, the problem was a lack of DPS in tank mode.
For this character it would be a monumental task to complete this on EPic Elite, and I have absolutely no problem with that. Some flavor of the month build probably has huge advantages over this build so that comment has to be taken with a grain of salt.
I clearly felt if the mobs maintained their level of damage (or doing slightly more) than a well conceived tank and smash party could easily complete this quest. However I am not sure how scaling effects this quest at the moment.
