As with any MMO or online game, you need to have thick skin. I have been the target of some salty players and i have seen players get the same treatment.

my advice would be just to try to ignore it. If its a reportable offense, report it. The worst thing you can do is get down because of someones salty attitude

sometimes one thing can set off a person, sometimes they can just be mean cause they want to.

and keep in mind that not all people are like that.

Today, i went into AK HM and got called bad when i was focused on the boss being at sub 10% and he had someone trapped. lucky, the tank and healer got him out, but it was an honest mistake. sometimes you get called names just because you made a minor error. He was mad because it could have killed him. Not wipe the party sub 10%, just killed him.

Went into another dungeon and got 2 of 3 commodations.

Morale of the story, people are pricks, and sometimes you just gotta brush it off your shoulders.
