I'm not trying to defend paladins, because I agree that currently ret paladins are hitting a bit hard and changes may be necessary, but the issue is that the game is not balanced for level 70 currently. I believe that at 80 the differences will be greatly evened out, so I'm very concerned that Blizzard may have a knee-jerk response to ret paladins in their current form.

That being said, they didn't take level 70 out of the game completely, and people will be pvping at level 70 years from now. There's no reason you should be unable to pvp at 70 unless you're a ret paladin, so some level 70 balancing is not out of the question. However, I think it's important it not affect end-game performance of ret paladins. I am VERY interested in finally getting a ret paladin in my raids, I've been too long without one because of prejudice. If a period of overpowered-ness is required to force guilds to be less adamant about keeping them out of raids, I'm glad to accommodate.
