Make a list what's wrong, and post it. Internalizing grief will only lead to a chronic illness.
I have done it... Many times...
No, Red jets do not get full loadouts much more than the western ones do. Not even Yugo gets full loads. I mean, we can totally do a variant of Orao with 8x FAB-275M-91 thermobarics, or the one with 5x FAB-500. Or we can do Su-24M with 3xFAB-1500. That one is really neat.
Should I make another list about this...?
And if you wanna talk about performance drops, what will you do about a F-4D Peace Pheasant I which flies just as good as all other F-4 phantoms... even though it carries 25 bombs and all the necessary pylons for them?
Yes, it is also funny and has such "real" loadout as Su-24 or Il-102...
