The missiles were nerfed because of the changes to speed. A few months ago the were boosted to combat speed tanking missiles but now that they are taking away speed tanking for the most part missiles are being changed to not make them overpowered, so it is less of a nerf and more of them taking away a boost.

As far as the mail changes I was hoping for more. I was hoping that they would be joining the 20th Century mail clients or maybe even the 21st. They are instead keeping the same old crappy mmo one.
