Hello World! (and forums)
If you hang around on the xwingtmg subreddit, you may have seen me around making the Quick Build guides on the core set and early wave ships. Last week I finally finished up and shipped some strategic musing on X-Wing related to the squadbuilding stage of the game: Building for the Planning and Activation Phases.
The article is here to read: http://teamcovenant.com/star-wars-x-wing/x-wing-building-for-the-planning-and-activation-phases
Enjoy! I would love to hear your feedback as well. 
Wrote my first strategy article for X-Wing on TC; would love feedback!
Excellent primer!
Umm... It is really interesting article. But I do not really see how a mix of two categories becomes a third, separate category..
Besides that, you could say that there are squads that are based on low-PS, mostly non-unique pilots while the other category is based on Aces, and the third category is a mix of pilots with different Pilot Skills... Isn't it the same in the end? Especially because we do not use that much of these PS aces that has poor action economy or decent special ability that compensate for lower action economy (otherwise their PS bid is not enough to pay their cost).
It's a well-written article (the most important thing!) and I like the way it used the journey of a new tournament player to frame the content.
However, I'm not sure your core concept of squad types entirely works. I've noticed a tendency among a lot of gamers to try to over-complicate things and almost over-categorize in an attempt to make things sound deeper or more "worthy" than they are. Sure, your concepts of "Activation Phase" and "Planning Phase" squads aren't exactly wrong but they are unnecessarily complex (incidentally, just like the word "unnecessarily").
You're basically talking about high-PS arc dodgers and lower-PS jousters (not exactly, but close enough). I don't think introducing your own unique terminology will help newer players. In fact, it will probably hinder them since I've literally never heard anyone use those terms before and if a newer player asked me for advice framed in your terms I wouldn't know what they were talking about.
The concept isn't even that clear until you get to the really helpful part of your article with the example squads. This works very well because the solid examples provide a clarity to your points that the vague terminology couldn't.
