Which is a fair counter-point. How much are people "wrapping"? My assumption was that it would be a fairly rare thing. Incidentally - I'm now remembering - this is also why it felt reasonably alright to have Field Repairs and Derelict Contingent be contradictory, since the difference between I8 and I10 is basically just a "boring" colony skill.
In my three vanilla runs so far I've wrapped in every single one. Granted, I have not wrapped around directly each time. But in two out of three runs I've gone I4, T5, C5, reassign all Industry skills for either T10 or C10.
A huge part of the reason why I wrapped was that a lot of ships I want to fly and "need" to wrap. While I can see how some of the combat trees and technology trees are supposed to be "mutually exclusive" playstyles between phase and shields, I echo the sentiment that many others have made that C10 and T10 actually really complement each other. Doom doesn't feel the same without C8, Odyssey doesn't feel the same without C10, and T9 is incredibly useful for all phase ships.
I've also never in a single playthrough felt that I wanted to just play with phase ships or just play with normal ships; I've always wanted to use both or have the option to do so at any point. I mean it's certainly true that I could fly a doom without any of the phase skills, but it's just not "fun" to do so. There are not enough phase ships for me to justify a pure phase specialization build without wrapping, but I also still want to fly phase ships at a moment's notice. So the solution is to always wrap.
