You forgot Ruthlessness. I'd say its tier 3 for now.
I disagree with R2-F2. Its too expensive and takes an action. Really only useful on Biggs and you have to stack him with focus to make it worth it. Usually isn't. Tier 4 at least, I'd even go Tier 5.
Same with Blaster Turret, but may be Tier 3 with the BTL upgrade.
Daredevil really has two homes, Tycho and Ociunn (and you really need EU). So I'd say Tier 4. It would be more used if it didn't have such a huge penalty.
Flight Instructor should be Tier 5, not because the upgrade isn't all that useful, but because its 4 points! That puts it into premium upgrade status. If it was 2 points, yeah I'd say Tier 4 is ok. I've never, ever, seen anyone run it, even pre-wave 4 with all the swarms. Now in the high PS meta its even more useless.
But other than those I think your list is pretty good.
Thanks for pointing out Ruthlesness...that made me realize I also forgot Dauntless...will add both of those later.
After some thought, I had moved Daredevil to Tier four, but must have used an older version of this list when I copied things over...I'll update that later as well.
I feel as if Flight instructor has a place, just not right now...it's not terrible if there are lots of PS1-2 ships around and you want to use a large ship. In my mind, Tier 5 is for cards that should never be used, no matter what your opponent is flying.
FI is terrible for 4 points. There are so many other defensive upgrades that are better for the points on a ship that can take crew. Isard, Chewie, C3PO, R2-D2, Recon Specialist, etc. Hell even an EU is a better defensive upgrade on turreted ships.
