In update 0.8.2 we implemented a method that granted a non-linear increase to the continuous damage inflicted to aircraft by AA guns. In cases where the number of ships sharing a field of AA fire increases, the continuous damage caused to the attacking squadron is lower than the total combined sum.
Checking the mechanics in 0.8.9, we found that the damage is no longer reduced as described above. The reason for this was a bug that appeared in version 0.8.7.
However, after analyzing the current state of aircraft carriers and their interaction with AA, we decided not to make additional changes. This means that the AA damage won’t decrease in any cases of overlapping AA zones of ships. At the moment both aircraft carriers and ships interacting with aircraft are in a balanced state when taking into account the latest global changes - rework of AA zones, updating the mechanics of the priority AA sector and large-scale balance changes. However, if in the future it is necessary to use these mechanics, we will be able to quickly turn on it back for balance reasons.
We apologize for the situation.
