This is a game. It is meant to be an enjoyable experience. While I can understand frustration in losing in a game, it doesn't mean I take my frustration out on others by belittling them and claiming to be superior to them. If you perhaps talk to them in a manner that is respectful and understanding you may get better results, they might take longer to learn things or simply new to the MMORPG genre in general.

I honestly hope you can be more respectful and if you cannot then I don't think the community would miss you if you decided to leave.
