This was an attack aginst pures, but Jagex didn't do it solely for that. They really did do this to stop RWTers, but they also knew that by doing this they could put a hault to pures. Jagex never did like Pures, whether they say it or not, they hate them. They exposed the stupidity of Jagex in the way they set up the combat system, and Jagex didn't like that, but pures technically didn't break any rules so Jagex never had a surefire way of stopping them. When they thought up of this to stop RWTers, they also probably knew that this would hinder pures greatly, and seeing as to how they hate them, they went through with it because they've always wanted to see pures fall, and finally had a way of going about it without just coming right out and saying it. They've found a way to stop RWTers and pures altogether. Like a previous poster said, it was an added bonus, it was a win win for them cause they hate RWTers and pures so they've gone through with it. I've heard though that in the past week only 27.5% of their members have logged in, so they're gonna have to do something or they're gonna probably lose a huge amount of reg subscribers.
