About those Level 70 AV items

[VoiceMan]

Ok, in one sentence they say that Rep will "roll over", and next they say you'll need to "start over". I can't seem to access the forum now on it, to check for context, (something about maintenance) so I'm still wondering what that means. I have a rogue who is maxed on rep from WSG, and is partway through honored with AB. The goal I have had for her is to max out on rep in each of the 3 BG's as a way to gear her up, as I don't anticipate raiding with her much, as she's not my main. She's only level 37 right now, and I would hate to have to start all over with the WSG rep and AB rep just to buy the leather and weapon items you can currently purchase if your faction reputation is high enough. Since I can't get the forums themselves, can someone shed some light on that?
