Notice how many ifs and personal opinions and assumptions about the other player and personal beliefs are all in this brief little paragraph? That's what I'm talking about. You think he wouldn't have noticed, you think he was putting on an act. Opinions are one thing, but do you expect this to convince anyone about anything if they don't already agree with you?
As far as I, as an outsider to this story, am concerned, it's very possible for you to be wrong about literally every single thing you just said. Obviously you trust your own opinions and perceptions, but how do I know that if I met this tank he wouldn't have a very different view of events? It's not unheard of (http://forum.square-enix.com/ffxiv/t...a-108-gear-LVL).
Also you don't have to alt tab.
I haven't seen any evidence to that effect still. The part I'm most unconvinced of being the "because of." I'm sure people get harassed. I'm sure parsers get brought into it. How/why would a parser ever cause it?
