Be nice.. please.. or just use common sense.

If you put in a bit of work beforehand, people are far more willing to help out. But if you do nothing at all, why should we? Give and take - you can't expect other people to do all the work for you.

I always watch videos of the boss fights in dungeons I'm about to queue for. I always explain that I am new the the dungeon, but have watched a video so I have a basic idea of what's going on.

That said, watching a video or reading a posted strat is far from actually doing it, and I appreciate when someone takes a minute or two to explain nuances or a brief summary that might not be entirely clear by just watching a video or reading a post. Not every dungeon has a step by step guide illustrating what to do, not to mention after watching several encounters in one go, information tends to get muddled or lost among all the bosses and their skills I just soaked in.

It definitely works both ways, but in regards to OP's experiences with people leaving after one attempt, it's not always about being unprepared. It's about not being an impatient child and understanding that the game, and a lot of the players are still new.

I find people being arrogant pricks just because they feel above wanting to spend a minute to explain, are just as bad as people coming in and saying "lol wat do I go guys? lol", if not worse.

Note: I'm going off the OP's experiences. I'm glad that you are considerate enough to help out those that do try.
