There's definitely been a change, and not a good one. You're not alone OP.
Yes, they were too easy to escape before. They need to make it more challenging. Now, however, it's made more "challenging" by two main issues: 1) the escape vector often moves around faster than I can rotate my ship to keep my reticule over it. If I was going min throttle when I got interdicted, I understand, but this happens regardless of ship speed. There are plenty of times when it's literally impossible to pitch fast enough to keep up with the vector. And 2) for whatever ungodly reason, I've had interdictions where I've LOST (I never lost once to player or AI before the change) DESPITE having my reticule perfectly over the middle of the vector for seconds at a time. In the worst example I've encountered so far, a fedsec eagle interdicted me and my bars were down to 3 or so. I got "lucky" and the vector stopped moving for a few seconds, in which I placed my reticule perfectly over the vector...and over the next four seconds I lost all the bars in spite of this.
I'm okay with making something more difficult. This, though, is like a "fake difficulty." If I fail to evade of my own accord, I'm fine with that. But seriously, failing regardless of doing everything you're supposed to be doing perfectly? It's not even failing to evade that makes me angry, it's the principle of the matter that I should be able to do so. This doesn't happen super often, but it's often enough that I grit my teeth and openly swear when it does.
