Phast, I have a few issues with this design and it's write-up.
1. The only Bf 110's on the Western Front at this time were dedicated night fighters. They did not conduct any ground attack missions between the Battle of Britain and the D-Day invasion. The only Jabo missions historically were conducted by the dedicated Jabo squadrons in the FW190 Jagdgeschwaders. Furthermore, the 110C-4b is grossly imbalanced against the Allied planeset. A 110G can at least be reasonably balanced in playabity against the Mossie given the correct loadout restrictions. But historically speaking, any Jabo runs would have been 190's.
2. Ordinance restrictions are not included in the design write-up. Will the Mossie and 110's be the only aircraft carrying ord or will other types also have the ability to bomb/rocket attack? If there are other potential attackers, what is their capability? How will these planes be balanced? How do the players know they can be or will be balanced?
Honestly, rockets should be disabled across the board since the Axis has no ability to rocket attack ground targets.
3. The plane min/max are unknown. This is another balance issue. How can the player base know that the event has been designed to be balanced when the plane minimums and maximums are not known?
This is potentially a fantastic event, but I have my concerns.
