I think that we're going to see historically inflated victory scores for the remainder of the year.
The behaviour of the AI is more appropriate to 1918 than 1916. I usually seem to be flying in 4+ flights and meeting similarly large groups of Eindeckers.

The AI is quite aggressive so it is often a case of kill or be killed. I have only been the attacker in one of my victories.

The greater chance of being killed in 1917-18 will even things out.
