Its not so much a change in the gunnery model as it is people are now flying to defeat the disapearing icons- not flying for angles as in 1.03.
I like the icon range changes for 1.04,same for fuselage/wing masking of icons,however I don`t care for the canopy braces removing icons as it penalizes planes with braces and makes a slight break turn defeat what would be a good gun solution. This feature has decreased some of the fun factor for me.
The "scooting" effect the disapearing icons produces is very frustrating,particulary for BNZ planes.
