After doing Athiss I can certainly agree with you there. I was so strange to see all these solo mobs as trash then boom random boss. Unexpected to say the least. But Athiss was not as hard as i was expecting, imo Hammer Station is harder than Athiss. Last boss included.
OH and minor off topic question. Is there an easier way to get out of Athiss than running all... the ... way ... back? the 18hr call to fleet stations isnt too useful haha
You're supposed to leave Athiss by clicking "Exit Area" right above your mini map.
