hmm while I'm pretty new to the para mine already has tier 1 survivor and I must say it was a rather delicous piece of cake.
I'd recommend focusing on defensive motivationn party buffs, sorry i don't have any builds, my para went with command and tier 1 was still easy.
But just looking at the skills available you'll probably have more longevity with a focus on keeping your party from biting the dust.
i got legendary survivor with my paragon almost a month ago just runninig into mobs and throwing spears in things faces, unstrippable defense buffs ftw
