So how is this supposed to work?
As we can see from the threat cards 1 Blue squadron Escort with Protorps, R3 and Sfoils is 2 threat, so 50 points.
Protorps are 8 points. (there is a screenshot of the app showing this value)
R3 is basically weapons engineer, so I'm going to assume somewhere around 4-6 points
S-Foils I think will be free.
Which means, approx. 36-38 points for a naked Blue Squadron escort (with S-Foils)
There is still the Cavern Angel, Initiative 1 X-Wing, which I presume will cost less.
This of course is not definite by any stretch, but it is a very likely estimation.
Which means, you can have 5 X-Wings, with some cheap upgrades... Possibly with R4 astromech (if that also keeps a low price)
So... At this point, the X-Wing has double health, better dial, shields, better actions, better attack value...
How is the TIE swarm supposed to defend against that? How do you beat it? They are inferior in every way imaginable. You can't outmaneuver them... You don't really have overwhelming numbers.
If you focus fire, you will take down maybe 2 ships, and that is the best case scenario. More likely you will damage 1, and kill the other. But you get wiped by simultaneous fire, or just get PS killed by Blue Sqd.
On the other hand, 2 X-Wings can take down a TIE... If we look at the best case scenario, the whole squad can take down 5 TIEs in a round. 
I don't wanna be petty (who I'm kidding) and I take no pleasure in this (yeah I do), but (here it comes) I told you so.
