A lot of these are good, but then some others are very questionable if not wrong.
M50 6.7 > 7.3 (small size, quiet engine, ability to rapid fire 6 rounds, very easy to bush up).
The M50 isn’t a Rakaten/USH: The launchers are offset and require notable corrections when engaging targets at range to maintain accuracy, let alone trying hit a specific area or weakspot.
Add the fact that M443A1 has terrible spalling (prepare to center mass a Tiger 2 and turn the crew yellow) and there’s no way this thing should be sitting at 7.3 when way better vehicles exist at 6.7 and 7.0.
(Also, you really should have included the M26 Pershing going 6.3>6.7, it’s awful to play at 6.7 and was perfectly fine at 6.3.)
T92 7.0 > 7.3 (Tends to bounce or eat shells, fast, small, very easy to bush and hide, potent HEATFS)
The T92 is perfectly fine where it’s currently at.
A lot of very important traits get worse on the T92 in comparison to the M41A1 just for very minor upgrades like mediocre HEAT-FS and slightly faster reload that cause a whole BR jump to 7.0.
Luchs 7.3 > 7.7 (better Wiesel but bigger with a 360 degree turret rotation.)
The Type 87 RCV (P) is already insanely terrible at 7.7, and it has the exact same weapon but stabilized; we don’t need another terribly over BR’d 20mm.
Df105 8.0 > 8.3 (10 shot HEAT mag, with a 5 sec load time, can bounce early APFSDS, and eats auto cannon rounds).
There’s no way the DF105 should be at the same BR as vehicles like the AMX-10RC and MARS-15 💀
Both of them are WAY faster, both have APFSDS, both have laser rangefinders, and both have similiar levels of survivability; the DF105 is perfectly fine at it’s current BR.
Gepard 8.3 > 9.0 (often used to zoom to a flank and wipe half a team due to great APHE, and it’s APDS can kill the heaviest of tanks, also way too good of an aa for just 8.3, it can easily down helicopters, and planes with ease).
It’s on par with the AMX-30 S DCA, which was raised to 8.7. It should go to the same BR given 9.0 is pushing it way too far for an autocannon SPAA with no HE-VT when the exact same vehicle with MANPADS missiles is 9.7.
Itpsv Leopard 8.7 > 9.3 (being a better, and better armored Gepard, it’s strange it’s only been one br higher. 9.3 is a good fit for it though.)
Same reason for objection to Gepard BR increase. Itpsv’s hull armor is completetly useless when any hit to the turret will insta-kill it via ammo explosion, along the fact that the 2A4 hull’s composite is incredibly weak and gets lolpenned by 105mm M111 Hetz (the 2nd weakest 105mm APFSDS and insanely common above BR 8.3).
