Guild Wars 2

I think the simplest thing to do is to allow players to return to an instance they were in for some amount of time after a dc. (same as it was old Guild Wars)
This will not only help in fractals, but any instanced content – dungeons, story and whatever instances will be added in the future.

Note: this is just a simple hotfix, and it will not solve all the issues with fractals, i.e. if a players leaves or is kicked. However, it seems to me that this solution cannot be exploited to kick other players in favor of guild members or skipping levels.

If it is really a simple hotfix as you claim, then ANet would have fixed it by now. If you know how to fix it please contact ANet since they are looking for good developers.

I’m no claiming that it is simple to implement (though it might be since they did have this functionality in Guild Wars). All I’m saying that this solution will solve a lot of grief and it should not introduce new exploits to the game. A better fix is preferable, but might require more time to figure out how to add one without adding more exploits.
