It all depends on the group. For example, there are people that cannot stand others lack of knowledge or not being able to complete the raid under an hour,lol, but their are others who would help despite the situation. I always try and help anyone in my friends list. I don't really care much on light level, the way someone speaks, or even if you speak at all. As long as you know what you are doing if not being able to ask for an explanation then everything is fine.
