Tankers can easily survive the alpha and sustained damage. The problem is damage. Super Strength provides a permanent 80% damage boost from rage, and you can time the crash between spawns. Footstomp is a 15' radius PBAE that also knocks the mobs down to prevent scattering. If you couple this with an armor set that possesses a damage aura (fire, ice, or dark) and you can farm pretty well.
If you plan on farming in a duo team, grouping with a kinetics support character will increase damage enormously. The second team member definitely needs to be someone who can either deal a lot of AE damage, buff AE damage, or both.
