Okay guys, enough already. Just... enough. I don't know why you haven't done this already, but you need to fix this crap because honestly, it's getting old. What is? The constant nerfing to please the PvPers or PvEers.
You can't do both. You can't -- at least, not with the same sets and skills. So stop trying because all you're doing is irritating everyone.
This is code... software, which means it's malleable. So if you have an armor set that rocks in PvE, but is over powered in PvP, either don't allow that set in a PvP zone, or adjust its properties while in that zone. Yes (gasp) that means that if you have a rockin' PvP set it won't rock as much when you're doing PvE. Better than nerfing the thing for everyone.
From what I've seen of this game, the hard core players (who are usually the ones complaining about stuff) spend a lot of time and energy tuning their toon to work where they spend their time: PvP or PvE. Causal players (and those players who insist that well... THEIR characters work just fine in both, and you just don't know how to play) tend to cross into both of those areas but don't specialize.
I spend almost all my time in PvE. It's just my preference, but I can tell you I'm getting very tired of building my toon (and I don't sit there and calculate out the absolute best balance EVAR -- I'm only a slightly more than casual player), getting it to finally survive something, then having those skills or armor sets nerfed because it slaughters everything in a PvPer's path and you can't be bothered to create the code to balance the set across zones.
The zone already exists -- it can't be that hard to change the armor/skill effects when you cross into a specific zone.
