I want to state my objections here.
But first a big welcome to the newcomer, warmly welcome
A level 90 Trader, any kind, with a good armor plus entertainer and medic buffs has no trouble whatsoever in a hunting group that knows the ropes. In fact, you do not have to make one single point of damage, as long as you are in the group your harvesting droid will trundle around and harvest whatever carcass he finds. Just stay decently close to the group's Medic but out reach for area attacks. Some creatures have a little further area, but you should do fine as long as you have a good Medic.
Perhaps the hardest creatures at Dath make for troubles, but honestly I doubt that.
Even if you do not need to shoot a single shot I still recommend that you bring your Traders best friend a shot here and there helps the group, but do not fire at a creature solo, then you takes its aggro
PS: I often have one of my Traders on follow on my combatant if I am out solo-hunting, and then I group the droids too to increase spawn size. But then I stay away from creatures that are known for area attacks as it blows my droids up.
PPS: Now I notice you are level 56, hmm, I would be careful but in a reeeeally good group it would work, just do not engage in combat when your health is not 100 %. That means, go away at times if your Medic cannot keep up with you. You probably need a friendly guild for this though
