Ran this with a 650 survival hunter with a pet. Died initially then it was fine for a while, then mysteriously chain died while I was sleeping so... no clue what happened. Didn't work out great though for me heh.
if you experience lots of death then perhaps use singular or a plugin that will use the garrison skill when you have more than 6+ mobs on you or HP is lower than 20% or carry some potions with you because it is very few moments in that profile you will ever use those. Mainly at the middle arena which has lots of spawn and that's it.
