With the advent of the R7 Astromech, do we forsee any Y-Wing Swarms with the new two-pointer?

I doubt it, for three reasons:

1) With no offensive action available Y-wing damage is pathetic, especially since "swarm" implies no turrets. You might stay alive longer, but only at the cost of any targeted ships not contributing anything that turn.

2) The R7 doesn't stop focused fire. You can only use it once per turn, then everyone else gets to hit that ship without penalty.

3) You have to guess which ships are the biggest threats when you target lock them. And then the ship you do target lock can just attack a different Y-wing instead.

Really the R7 is a pretty limited upgrade. Tarn Mison is going to love it, and it might have some interesting potential with lists that can pass around free actions/TLs, but most of the time it's just not going to do very much.

I'm gonna say meh about this as well, given how Y-Wings already only have so-so attack and defensive countermeasures as well. Unless it's a list that can generate tons of target locks (Dutch with R5-K6) it's an underwhelming prospect. I'd much rather make use of that new R4 unit that's coming with the Transport instead.

I think Y wing swam only works with

5 Gold, 2 with Ion

or

5 Gold with Flechette Torpedoes

or

Dutch with Ion

4 Gold

I'm going to find a competitive squadron for R7-T1 on Dutch. TL, pass free TL, Boost out of firing arc, Ion Turret!
