I re-started playing FF a couple of weeks ago, so consider me a complete beginner. My main, and up to now the only class, is 54 NIN. I am the point when you realise you still have close to 100 quests to do, before you can continue with leveling your main, so I decided to try other classes, maybe some crafting or gathering.
But even before this decision, I sometimes found myself missing a skill or using incorrect sequence, especially in situations where there are a lot of visual effects, moving around or special mechanics to do. I will get better and improve, but by the time I get to 70 and start using even more skills and even more combinations, I will not have improved to the point of being perfect. Simply put, this will never happen. So, even when I am at 70, having succesfully finished all dungeons, raids or whatnot, I will still make mistakes. There's no doubt about it. And that's only by playing one class/job. What if I were to play more than one and I would often switch between them?

So, the question is ... What do you do when you encounter someone like that in your group? How long do you wait before you say/do something? How certain are you that you know the reason for this person's mistake(s)? Do you ask "What happened there?" before you start giving advice or even your personal feelings towards someone like them?

I am not saying "do nothing" or "say nothing". But, what's the point of you telling me I am bad, when I know that perfectly well? I am sitting behind my keyboard thinking "Concentrate, you fool. Or it could be another of those dungeons where two or more players are trying to outdo each other with "knowledge", "skill" or "understanding of the game" while the others are waiting from them to finish".

Please, all of you with knowledge and experience, continue to help, educate and lead us, the beginners and all the others with lesser understanding of the game. But understand one thing, while it's perfectly acceptable to expect "very basic level of competence" in playing the game, it's equally acceptable to expect "very basic level of humane behaviour" of someone who joins other people for group activities. Empathy, compassion and sympathy are not just words.
