Standings seem simple enough. Go below -2 and no one wants to talk to you. Get it higher and you get better missions. Agents like it when you do their missions. Agents don’t like it when you decline missions. Agents are part of corporations. Corporations like it when you do their agents’ missions. Agents can get new missions over time.
So I did some missions for Hedion University’s agents. But then their agents didn’t offer any missions after the tutorial ones. So it seems there is no way for me to interact with HU agents.
OK, let’s try something different. There is a distribution agent in the Klaalakitoa Corporation. The agent has a distribution mission (which is a part one out of three for some reason). Why this takes 470 mm of cargo space, I don’t know. I finished it. Yay! So I got some ISK, LP, standings with the agent, standings with his corp and… hey why didn’t I get any standings with the Caldari State? It’s one of their corporations. Maybe Empires don’t care about distribution missions and only care about security ones? I don’t get it.
