Is it so hard to see why people are mad? Some scrub has <200 skill and a weapon that he didn't complete alone. He probably had people working for him to get that item, and he doesn't even spend the time to make the most out of it. That's why people should be mad.
Yes, if you have an Ukon and sub 200 Gaxe skill, AND have the stupidity to post a screenshot basically bragging about your awafulness, people will post trolling comments.
Except at that point, it isn't really trolling, it is stating the obvious. Attention ***.
