It requires that you play sub optimally, at cross purposes with strangers, and cannot be pursued directly. I have failed on nessus twice while making every attempt to complete it. I just had someone go AFK after we completed the first 10 and we missed a headless when the last 3 circles appeared. And it wouldn't be *that* annoying if I could CHOOSE TO LOAD INTO NESSUS but I can't I just loaded into earth, moon, earth, moon, earth, europa, europa, europa, earth, moon, earth, moon... I have to load into 1 of 4 and then leave before trying again. WHY? WHY WOULD YOU PUT SOMETHING SO STUPID IN THE GAME. IT'S LIKE RUFFIANS. Developers encouraging griefing and forcing players to go through some pointless process to even participate in the game is unacceptably stupid and poor design. Stop. It. STOP. IT.
