I noticed that there aren't limitations in sections based on quests. It's not very wise to make a whole area open to the player when a certain quest has not been done.

Example: I defeated the miner (with the help of my lvl 30 guild master) in Delta 7, when that wasn't my quest. My quest was to find the randomly down Cycorp agent. Which didn't end the level obviously because you have to beat a boss. A quest or two later and now I have to defeat the miner, which is near impossible because people keep leaving.

My idea is that when you beat a certain quest for a certain level (if you have any active quests) the level should end when you obtain the correct quest ender. It shouldn't be a loop of continous nonsense that makes you upset when you have to beat or obtain information for the second or even third time.
