The quote that is inciting the most controversy is:
Judgment of Justice is intended to be the gap-closer for paladins.
Ghostcrawler is getting a fair bit of flack for this statement. However, I think he just used the wrong word. JoJ isn't a gap-closer, but is more of snare. However, using the word "snare", would be impolitic. In a little bit of sophistry, JoJ isn't technically a snare, which means that anti-snare mechanics like druid shapeshifting don't work. JoJ is designed to be the "glue" that allows a paladin to stick to her target once she is in range.
Personally, I don't PvP, so I'm not too sure how good JoJ is. I think it would be neat if it had an additional constraining effect. Something like "prevents teleportation" so the target can't Blink or Demonic Teleport away from the paladin. Another amusing idea I had was that JoJ could prevent the target from changing form. So if a priest was in Shadowform, JoJ would prevent him from dropping out of Shadowform.
Q&A in General
In general, nothing new or interesting came up in the Q&A, other than Ret would get an interrupt effect. I got the sense that Blizzard feels that the paladin class is finished and complete, with only minor tweaking to be done as needed. So if you're not happy with your paladin spec playstyle, it's probably time to switch classes.
