I have gigabytes of screenshots from all over, most of them are from Ner'zhul, but a good chunk came from walking by a player on some far flung server and asking, "Hi, I like your set. Can I share it?" Often, it lead to conversations about specific style choices, or tribulations regarding acquiring that last critical piece of the set. Those interactions lead to thinking about sets from different standpoints, allowing growth for anyone in the discussion.
I'm glad that this community has many strong voices willing to share what they've created. You've made this the most enjoyable part of living in a world of pure imagination. I'm glad to name a number of them as friends, or at least good acquaintances. They really make this game worth playing.
When it comes to sharing, I don't hesitate to flaunt a new set. Good or bad, it doesn't really matter. Just the idea of a new set usually ends up being thrown onto Twitter as fast as I can type "/share" inside Warcraft. I think that is the beauty of the whole concept. You can create something that is uniquely yours just by changing a few, or even most, of the items in a set. What you've created distinguishes your character, both in looks and in style. To that, I tip my hat to all of you. You make this community great.
Just remember the important thing is to have fun. Oh, and of course...
MOG ALL THE THINGS! :p
