I even think in the case of anomalies the first question (do you want to engage) is redundant because if you say yes you get the window with fleets anyway. I think the first question should be removed and the window with the fleets should get the "abort"-option. It would save one click per anomaly battle - since you need 2 clicks to start a battle on anomalies, that would be 50% less clicks.

There are currently only two types of battles with anomalies. 

1) Defended by two pirate small vessels 3 attack..zero defense 

2) Precursor anomalies, defended by 6 high beam and 1 high beam for a total of seven defenders None have defenses but do have at attack rated around 60. Ideally one ship with 65-70 shields and two weapons can take out a single one.
