Your better off fighting in a python than an anaconda

there you go I've saved you 100mil!
I would agree with you if the Python was not getting nerfed hard.
As it is, An A grade python can be defeated by a D Anaconda with a little bit of luck (Opponent who is not experienced fighting player condas) and a well placed ram to knock off the shields wile keeping your own up.
The build is not only an answer to that, but a upgrade in some regards as well for about the same price. If the A grade thrusters where better then what they currently are, then I would also recommend those as well, however as it is you go from boosting at 250 to 270 for 50 million, and since you are reversing most the time when fighting other players.. Well the boost doesnt give that much out of it.
What the boost does have over the Python is that it lasts over 5 seconds.
Between the Python and Conda, one is an offensive craft, where your goal is to find and kill opponents before they get into a dog fight with you, in addition to being able to run down opponents and kill them, the other is defensive, where your primary goal is to defend ones self, by scanning for targets and placing them in your sights wile determining weather or not they are a potential threat if they get on your back, and forcing a catch up joust if they engage you by reversing , not to score the kill against the player unless they seek said death. If they chose to run, you cant do anything about it. Then again, if you do as well, neither can they.
Post nerf, the Python is going to turn defensive, and the Conda is better suited for that role all around. The build however is just a starter Conda. From that, upgrading things to A will see you marginal gains, with the big one being in the class 8 PD, but none of them will be necessary, just nice to have once you can afford them. Thats why the build is meant to replace the Python post Nerf. They both are going to end up doing the same thing anyways.
