Yeah, I brought it up on the paladin forums. Whenever I looked for Ret pvp talent builds I was always disappointed they always pointed at the "Reck Bomb" stuff. So this made me rather relieved.
Overall though I'm happy Blizzard made this post to show what things that are intended, and not bugs. Hopefully we'll see more of them because I didn't even think of some of these things - like the Tauren hitbox / weapon reach, it makes sense but I didn't really think about it!
