You talking NPC haulers or player? Did the NPC thing in the first year but CCP caught on and nerfed that. If it is player than ya, you need a group too bring it down before Concord gets there and one guy waiting nearby with a hauler to steal the loot. I am a solo player so it doesnt work for me.
Two thrashers can pop shit like a Mammoth in 0.5 space p. fast bro I do it all the time.
