Sorry to say that, but it's my personal opinion that like 80% of the players, in every online game, in every country, belonging to human race, joins to be a troll only. Everyone has been a lowbie, almost everyone met once or more someone that was not nice. This could be caused even by a football match, imagine here.
Don't worry about it, prepare yourself and your char as better as you can, but always remember about these moments if you will level up and be highbie yourself. Many assume an unkind behavior immediately after this.
