so I played 3 games last night, TIE Swarm (X6) and A-Wings (X4).
and I proxied the version 3 in the above post, I must say it was really good.
it helped both squad push damage which is something they lack.
naturally I rolled all my crits when I was on side 2. But mostly the first shot striped a token and then second got 1 damage in.
