Checkpoints in Story Quest instances?
That particular mission is very annoying even with a perfect connection. Underwater combat, ugh… I have no idea what Anet was smoking when they thought it up.
Dont get your hopes up for any sort of fix, there nothing that will be done about this at this stage of the game. Try it in the middle of the night perhaps? If your internet cant stay up for 20-30 minutes straight you have a more serious problem than not being able to finish a story mission :p
Also try seeing if someone will help you run it. That way you should get to the end of it quicker and reduce the chances of your internet going out on you.
There has to be a way to make that work, because right now, the only thing I like better about other MMOs is that my Internet can go out while I’m in an instance and I know I won’t have to start at the beginning again when I sign back in.
“a way to make that work” actually exists in GW1. That feature didn’t exist at launch though. As long as you can reconnect within the time limit disconnects weren’t an issue.
A slightly different but similar thing also exist in Path of Exile. Instances there have a 15 minute idle timer. You can disconnect/crash/whatever but as long as you get back within 15 minutes you can resume where you left off. It also provides a way to start a new instance instead of resuming in case you want to restart.
