The problem here again, while this can be viable on offense, it leaves you open on defense, as the previous mk6/sa counter. You will be the easy target on the shard with this team on defense.
I noticed some odd stuff happening yesterday as well, I thought they had possible rolled back changes. Someone left Bomber/SA/Malgus on defense. I thought great, easy battle. Of course lose the opening coin flip (probably 25% at best opening coin flips for me since change). TIE dagger on opponent never came on the field, but somehow, I couldn't get ahead of opponent on the TM train. They stayed consistently ahead the entire match. I started dagger, malgus, bomber. I think that somehow with dagger in the hanger, the team still got the benefit of it. Otherwise I should have jumped ahead of them because I could gain tm while they shouldn't have been able to. After they reached ult, they started annihilating my ships like they were paper. This had never happened before the changes. It was a weird battle.
