What profession is everyone this is happening to ?

It happens a lot with my adventurer, but never seen it with my trader, fixer or doctor.

If I try to pull mobs to the first mission room it almost always goes wrong and others aggro me from several rooms away. This does not happen with my team members.

Also, often I get aggro for no reason. Other teammembers can already be in the room with the mob, I go near the door and the mob will attack me. Or sometimes, when team has already hit the mob, and I have done absolutely nothing yet, the mob will target me anyway. Especially trader mobs aggro me often. Weird. I'd like to know what's causing this. Is it a nano I'm running ? An item I have equipped ? Or just the fact that NPCs hate neutrals ?
