To op.
Don't let these kinds of people turn you off, this game is great, and surely there are very nice people as well. It's just like in real life, there are always a holes that have no patience and think they're better than the rest of the world, pay no attention to these types of people and do things you enjoy. Don't let them stop you from progressing the game or trying new dungeons, if you are yelled at or verbally insulted, just leave knowing the person trash talking is just a sore loser who thinks he is god behind his keyboard at home, so don't worry and have fun there are many nice people within the community who are level headed and understanding who won't trash talk to you. If I see a person die over and over or not dodge there's no way I'd yell at him or something.. it's a game and I expect the same from the people I play with when I do something for the first time as well.
