I do. Again, I want to give lengthy answer, im just checking whenever I will get the same “No.” or not. I wouldnt bother with these questions in the first place if I didnt want to hear your opinion.
Anyway.
While obviously offensive capability isnt everything, as it is apparent from BR difference between CS5 and CS4 which is solely, to my knowledge, due to CS4 lacking the additional CMs, offensive capability seems to have the biggest weight on BR placement of a plane, at least when it comes to missiles and ARB.
Example would be the KWS, which is effectively F-4F, a 11.0 airframe, with better missile capability in form of better radar, IRCCM missiles and ARHs, which catapult it to BR of 13.0, while their flight model and defensive capablity remains practically the same (RWR is effectively the same, being ever so slightly better on KWS).
EDIT:
Another example of missile or offensive capability having bigger impact on BR placement than defensive capability would be comparison to F-4E and F-4F, with F-4F sitting 0.3 BR lower despite having better RWR than F-4E.
Another example would be the 12.7 MiG-29 and 13.0 MiG-29G with only practical difference being again better missile capability when 29G gets access to R-73s while defensive capability and flight model being the same.
EDIT:
Another example could be the MiG-29 Sniper and MiG-29 9.12A/9.13, identical planes when it comes to ARB, sitting at identical BRs but Sniper has much better RWR.
Another example would be Tornado F.3 and F.3 late, which is the same aircraft just 1.0 BR higher again due to better missile capability (and two additional DL channels on its radar).
EDIT:
Another example could be F/A-18A and US F/A-18C early. Identical planes, identical defensive capability, but F/A-18C early sits higher due to having 2x more hardpoints for Sparrows and having better Sparrows.
So, a MiG-29 9.12A/9.13 that would lose R-27ER and ET while gaining access to up to 6x R-73s would be better in missile capability than CS5 given that it can carry more missiles in total when compared to CS5 as well as R-27R, despite being clearly worse than R-27ER, still being better than 530D.
Due to that, Id argue that MiG-29 9.12A/9.13 with 2x R-27R/T and 4x R-73s, alternatively 6x R-73s, would be better than CS5 by a large margin and as such they cannot share BR with current BR spread and MiG-29 would have to be placed higher (and we would again run into issue with compression but thats another story).
And, arguablly, the missile capability or offensive capability as a whole seems to be most important when it comes to actually deciding who gets to win since you could have the aircraft with the best defensive suite in game but it would be useless if it cannot engage the enemy at all. Not saying CS5 cant engage the enemy at all, but its frag potential seems to be much lower than this would-be MiG-29. On the other side of this argument, plane with no defensive capability but with insane frag potential would still be able to win games.
