I have to agree. Although I am a high level myself, I take no offense.
High level braggers, do you remember the time when you were in the shoes of the low level people? Have other high level people ever bragged to you about their high level? Did it feel good to have those people rub it in your face? If it didn't, why are you doing it now?
I believe that high level people are supposed to help the lower levels grow into the high levels. High levels should be mentors to the lower levels. Though of course, that is just my opinion.
If you're not mentoring, you should at least be encouraging the lower levels.
One time, I was in an uncommon realm and saw two pirates battling. One was like level 38, and the other was a level 6. They were talking nicely, and the higher one was trying to encourage the lower one. When the lower one said, "I am a noob for trying this." Instead of saying yes, or lol, the higher one said, "At least your a trying noob. Which is better." If only all higher levels can be like that.
