This is what I use for auric games when i play purge.
use BB on snipers/bulwarks/crushers that are far away you can also melee the crushers with Deimos using uncanny LIGHT 1 HEAVY 2 combo as that does good damage and staggers them very well be careful with the special as it has an animation lock
swap deflector for executor for extra soulblaze damage*
uncanny/unstable force is a also fine for deimos. for purge staff flak and nexus are essential flurry somewhat less so other choices for the second perk can include unyielding/maniac/elites but I like crit most up to you really
for purge staff make sure to get a staff with at least 76% burn and cloud radius as high as possible damage and warp resistance are the least needed stats on that staff. yes damage does not effect its damage.
*uncanny and executor stack up to 4 stacks with a single weakspot special activation on any trash mob
