Here we go, not the same tweet, but same response: https://mobile.twitter.com/TheLegendBlue/status/628662111913119744

Sadly, that's what I was trying to find again when I posted this--it was posted by a user who asked the question this morning. I cannot quickly find the link as of this time, but if you search the forums for the keywords "34" "Taken King" "tweet" "proof" and browse through the results, you should find a post with a direct link to said tweet.
