Yeah we can only speculate why they put Mirage on BLUE side. But both options I have in mind still doesn't work well, even if we assume MiG-21 will be fixed before round start:
1) They decided to put Mirage on BLUE side because of whole country setting, lol OK! So let's put KA-50 on RED only, Su-25T on RED only. A-10C on BLUE only.... And mi-8 RED, huey BLUE...
Where is logic in that...
2) THey decided to put Mirage on BLUE side because it has counterpart like MiG-21 on RED side. Again I don't see logic in that.
Counterpart of MiG-21 is Mirage F1!
Counterpart of Mirage 2000C is MiG-29!
:dunno:
