one anecdotal experience in a global chat that is known for not always being the most helpful isn't really reflective on the state of the game. While the experience you had was a negative one and it's a shame that it happened, you would have eventually come across these types of people because it's the internet and just because they happen to be a mentor doesn't mean that they are always going to be positive and helpful. I personally wouldn't let this prevent you from actually enjoying the game, just ignore it and move on. You kind of have to when it comes to MMO's because this is just how it is.
