Just because it's not broken anymore doesn't mean it doesn't need a nerf lol. When 70-80% of your routine PvPers are all wearing the same set that's usually a strong indication.
Gonna be honest, I think a lot of people are overestimating the amount of players actually running Mara's anymore. I've gotten a handful of whispers saying things along the lines of "nice Mara cheese" and I'm not even wearing it. It's a very strong defensive set, but far from the broken mess it was.
