I have zero interest in the pre-made ships; the fun of the game for me is designing and building my own. I don't have an issue with newer players wanting a pre-set to get into a specific activity though. I've had a few friends start the game wanting to get into mining, but having to do other activities for hours before they can get a ship big enough was a concern for them, similarly for getting into AX gameplay. Yes, those experienced CMDR's amongst us can be mining in a Python in no time at all, or attack Titans in a Diamondback Scout, but that's not the new player experience. These unoptimised prebuilds allows them to jump in with both feet.
Zero rebuy on these also doesn't massively concern me. There's already players flying around in free give away ships, with free modules, etc. Once you're past a certain point it becomes largely irrelevant. The one caveat I will add to that position is that we shouldn't ever see large, or the expensive end of medium ships on sale for ARX. You don't need that end of the scale as a starter pack, and you should always have something to work towards yourself by actually playing the game. Prebuilds should be an introduction to an activity, not meta builds. They'll learn not to fly without a rebuy once they've started upgrading their build, or bought a bigger ship.
Early access Python Mk.II I'm iffy about, but at least everyone who has consistently supported the game (bought Odyssey) gets it in three months. I have no issue with charging Horizons only players for it, it's new content, and they haven't bought into the latest DLC. While I can see the slippery slope towards paid only ships, and I don't want to see that happen, I really don't see how that'd be any different to things like car packs in Forza. What's worse in games like that is the FOMO cars that are only offered through time-limited events, which we already have with CG modules.
