In the interest of keeping DDO a fun experience, I would like to offer some suggestions on things we might do to avoid stress and drama, and to keep things more pleasant for everyone.
1) Pay attention to what's going on. If most of the party is below half health and the healer is screaming "Wait!" that might not be the best time to go running down the corridor towards that pack of troglodytes. I realize it's the dwarfy thing to do. But remember that there are real people behind the dwarves and they might not enjoy being as dwarfy as dwarves do.
2) Try to stay together Generally one person will be leading a party. Try to stay with them. However, if people do get separated it's better for the leader to notice that and try to get people back together. If one person charges ahead and completes a dungeon while other people are dead and lost, those other people are probably not having very much fun. And we're here to have fun.
3) Avoid unsolicited party invites. If you ask on guild chat who wants to do some quest, and someone does not respond, that probably means they don't want to go. Understand that other players are not at your beck and call and may be doing other things. If they want to go, they can say so. Don't throw an invite at them anyway.
4) Listen to what people say. If you suggest something, and someone says no...doing it anyway and expecting them to run after you probably isn't the best way to ingratiate yourself to them. Just because they say no doesn't mean you can't. Certainly you can. But don't be surprised if they leave and do something else.
5) Communicate. If somebody has been waiting for you at the quest entrance for several minutes, realize that they probably aren't sitting staring at the screen wildly spinning their mouse so they'll know the second you arrive. If you rush up and go in the quest entrance, they might not see that. If the first indicator they have that you've arrived is hearing you cussing about being unable to find something inside the dungeon, leaving them to wonder how many minutes they've been waiting for you outside after you went in without telling them, that might not be the best way to let them know they can stop waiting.
Anyone have any other suggestions they'd like to contribute?
