I have raised this issue previously around the time it changed, 4.35?
I think everyone can appreciate the realism argument but why not have a channel that gives us the legacy open channel for those of us flying SP? Very little happening on channel 5 for me so it doesnt scratch the itch.
Once the air war dies off its too much of a snoozefest to bomb truck back and forth in silence so i just roll a new campaign.
Yes i understand joining a MP squadron sorts this issue completely but not everyone can - kids/life
