As someone who has encountered this 'feature' which has rendered the python a glorified rebuy shortcut, I can say that the AI is not inherently bad, I sat in the dock in my backup conda for a few hours, reading threads and the like and eventually decided to brick it in favor of a much more affordable Fer De Lance. Now, the AI when it isn't using this new instakill 'feature' is surprisingly not as horrible as i expected, my first taste of the AI being in my python for about 3 seconds, my head was full of questions, what do i do, that was A rated equipment, I can't improve that without engie mods and I can't afford to do that right now! But it turns out, the fer de lance, with roughly similar shield strength as my 4 pips python, can tank easily 10-20x the fire that my python could. Once the AI is not showing you the new 'feature' added to pythons, it's quite fun. Now as for my friends, 3 of them 'main' pythons, two have moved to a different ship after 10+ million in losses, another has stopped playing all together and that's honestly just sad. Every ship should be viable in some way, and glorified fireworks displays is not a reasonable function.
tl;dr; The AI is a challenge, but fair and easy to overcome with simple tricks like pitching down instead of up towards them to get them back in line before they can get back to your blind spot, and if you think that the death protrayed in this video
