No one cares WHY you are unable to perform your role in DF. They don't care if there's a thunderstorm. They don't care if your on a boat in the middle of the Pacific with spotty internet. They don't care your baby woke up or your cat jumped on your keyboard. If you cannot perform your role in a DF fight properly, all people want to know is if you can fix it/get better so they have a chance to complete the content. People join DF to complete a duty, not be told excuses/reasons why they can't (reasons and excuses are synonymous in DF. Again, no one cares WHY).

If your situation that prevents you from functioning isn't your fault, you have my sympathy, but that does not translate into a carry. People are not obliged to drag along with incapable players just because they have a 'good reason' for failing.
