China
J-7D
ARB: 10.7 → 11.0
Performance between the MiG-21MF & bis, but best-in-class missiles even though they are only rear-aspect. It is only at 10.7 to milk the disposable income of the large Chinese playerbase. Abused by skilled players and low skilled players alike. Blatantly undertiered.
F-104G
ARB: 10.7 → 10.3/10.0 - no flares, fewer missiles than the F-104J. Maybe move to 10.3 and adjust down from there if it still struggles.
JH-7 (& premium version)
ARB: 11.3 → 11.7
Missiles and flight model are definitely way too strong for 11.3.
J-2
ARB: 8.3 → 8.7
MiG-15bis equivalent. Currently undertiered along with most Sabres & MiG-15/17 variants.
Shenyang F-5:
ARB: 9.3 → 9.0
Similar flight model to MiG-17PF, Lim-5P. Two PL-2s aren’t worth a BR bump.
Russia
Eremin’s Yak-3 (early)
ARB: 4.0 → 4.3
This actually has better performance than the 4.3 Yak-3 at the cost of some burst mass. The Russian 12.7s and 20mms hit like a truck anyway. This has no business seeing 3.0 planes. Regular Yak-3 (USSR & French) could go up 0.4 to 4.7 as well without noticeable impact on its effectiveness.
MiG-15/17 family
All Air RB
- MiG-15: 8.0 → 8.3
- MiG-15bis: 8.3 → 8.7
- MiG-15bis-ISH: 8.0 → 8.7 - Minimal performance hit from the MiG-15bis. Closer to bis than MiG-15.
- MiG-17PF: 8.7 → 9.0
France
F4U-7 (France)
ARB: 6.0 → 5.7
No reason for this to be 0.3 above the F4U-4B with a worse flight model now that Ground BRs are separate.
NF-5A
ARB: 10.7 → 11.0
The raw performance actually exceeds the F-5E flight model at almost all altitudes in WT. It also has equivalent armament to the 11.0 E models. Doesn’t deserve 11.3, but it is, again, intentionally undertiered to capture that premium money. Closer to 11.0 F-5E than 10.7 F-5C.
Germany
MiG-15bis
ARB: 8.3 → 8.7
Undertiered. Very strong already compared to current 8.7s.
Lim-5P
ARB: 8.7 → 9.0
Undertiered. Very strong compared to other 8.7 & 9.0s.
F-104G
ARB: 11.0 → 10.7
Weak compared to existing 11.0s, let alone 10.7s.
Italy
F-104G
ARB: 11.0 → 10.7
Weak compared to existing 11.0s and 10.7s. Only 2 missiles.
F-104S:
ARB: 11.3 → 11.0
This is seriously higher than the MiG-21bis family and the F-4EJ???
F-104S.ASA
ARB: 12.0 → 11.7
Compared to the 11.3 F-4E, it has slightly better missiles but lower number. It has better top speed at low altitude, similar acceleration, and much worse maneuverability. Comparable missiles to 11.3 F-5E FCU with much worse flight model. 11.7 is a good start, but 11.3 could be justified.
Japan
R2Y2 Family
ARB: 8.0 → 7.3 for all
Just because Gaijin have removed these and are pretending they don’t exist doesn’t mean they can’t adjust them. They intentionally gave players a month to grind them after first notice, plus many have used them for a decade. They have also been adjusting other removed vehicles like the Coelian as well as rare/unobtainable vehicles like the Ro.57 Quadriarma
Britain
UK Phantom Family
All Air RB
- FG.1: 12.0 → 11.7
- FGR.2: Add AIM-9L and leave at 12.0
- F-4J(UK): 12.0 →
11.3 11.7… OR …add AIM-9L and leave at 12.0
The 12.0 range is horribly compressed right now, but these would be a good start. Could also make the argument of adding SuperTEMP to the FGR.2, but then it would be better than the Tornado F.3. There is no way it should go up to 12.3 though.
USA
Sabre family
All Air RB
- F-86A-5: 8.0 → 8.3
- F-86F-25/35: 8.3 → 8.7
- F-86F-2: 8.7 → 9.0
F-111A
ARB: Stay 10.7 but remove AIM-9B, add AIM-9E stock, and add researchable AIM-9J
AIM-9B at 10.7. Absolutely ridiculous.
F-14A (EDIT: late addition)
ARB: Stay 12.7 but add AIM-9L.
MiG-21bis has R-60M at 11.0. Rear-aspect Fox 2s are pretty limiting at this BR compared to other enemies.
