Heavier (probably) due to backseater and has weaker engine. Also limited to 6 Sidewinders (Supposedly never had 9Ls. Most photos show it with either 9J or 9E even)
For comparison, F-16A with F100-PW-200 has combat T/W ratio 1.15
F-16/79 has combat T/W ratio of 0.81
This fighter (F-16Aβs) is practically begging for a custom MM; instead of 1.0 +/- (11.3β13.3), it should be set to 0.7 (11.7β13.0), which would make it much more enjoyable to play, and planes set to 11.3 would be happy too :)
The best solution would be to compress the BR to ~15.3-15.7, but until then, an individual MM (0.7) for certain aircraft would be a decent solution in my opinion.
Calling for a matchmaking change is just allowing Gaijin to be lazy with balance. Its a horrible stopgap solution that gives Gaijin the opportunity to be lazy and delay much-needed balance changes.
