I always ran PD before, whether ballistic or energy, whatever I could mount. Energy PD was always inferior to ballistic PD, but that's because ships with many energy mounts typically have better shields which compensates for that fact. The new missiles are much more dangerous, I don't think anyone will disagree there, but I don't think they are too much so.
Now, more than ever, proper flux management, shield use, and maneuvering are vital to survival against missile equipped enemies. I don't find that I have much trouble with missiles as long as I can get my shield turned around to intercept, or maneuver so that my PD has more time to address the threat. When I make a mistake, or allow myself to get overwhelmed, or get too eager, that's when I get smoked by missiles. You can still dodge a reaper if you're keeping your enemies at arms length, unless they pop off a smart shot which doesn't happen all that often.
So, the new missiles have increased the difficulty, and as far as I'm concerned, it's been a long time coming. You shouldn't be able to run around in a frigate or destroyer and destroy entire fleets. You should have a very difficult time going head to head with a heavy cruiser in a destroyer. Can you still? Yes, but it's much more difficult than before.
Now, have the new missiles made it that much easier for players? I still don't think so. Ammunition is still very limited. You only have 2-3 volleys with any size mount, and if you don't use them wisely they didn't do you much good anyway.
I feel like missiles are finally balanced, is what it comes down to. This is of course my opinion, but that's why I started the discussion. I'm providing input and feedback, that's all.
