What is the current backlog of ships needing to be converted to master modes?
TL;DREssentially every ship still needs converting; master modes will reach the PU in stages, starting with speed tuning, then archetype handling, then per-ship differences, with no timeframe given beyond pointing to the public roadmap.
Well, the proper answer is all of them. I can't check how many flight controllers we have, but it's definitely in the triple digits. When we're going to move this stuff over to the PU, we will not do it all in perfection at once. So we're probably going to have the speed tuning first, so basically limiting how fast the ships can go. Then we're going to implement the actual handling changes of the ship archetypes, meaning streamlining all the ships so that they feel similar, bespoke to the archetype that they're supposed to be in. And then we're going to go to the individual differences. So this will be a multiple-tier thing, which basically will take some time. I don't know how long that will take. This will be on Rich Tyrer's team, so he can probably give you a better 'when' answer, but it will come in multiple stages.
It's one of those things where we invite people to always look at the public roadmap. That's your best indicator about when anything is going to come to a particular patch.
