Why did my thread get deleted?

http://boards.na.leagueoflegends.com/en/c/live-gameplay/stNsAjbY-i-miss-the-old-ahri-we-need-more-jack-of-all-trade-champions-and-why-riot-needs-to-get-qwe-right

That ^ was a thread I made and now it's gone.

Did I break a TOS or something? Place it in the wrong forum? Did the mods ninja it? Did the forums eat it?
