Ok, so there are good and bad that I’ve seen, but I’ll separate it per the vehicle category type (very long ted talk coming right up):
Ground:
I’ll discuss the elephant in the room first being the 90mm autoloaders of the French, specifically the ones that are raised to 8.0 in BR. They shouldn’t be raised to a BR where their rounds are generally reaching the obsolete area. Especially at the price at generally removing a lot of the 7.7 line up. They were already facing tanks with stabilizers and APDS/APFSDS already before the raise, there are no reason to make them face tanks that has an even better armament than before.
Second, are the discrepancy of raising the AML-90 to 7.7, but ALSO raising the EBR '63 to 8.0. I fail to understand the logic of needing to raise the BR of the EBR '63 as well considering both the AML-90 and the EBR '63 are two vehicles with the same gimmick (being a light, fast vehicle for scouting and flanking purposes) and also barely any difference in gun performance (both uses the same round, same gun performance in all regard like reload, muzzle velocity, etc.). Even more so, there is a Light Tank that has an autoloader with faster reload and a better velocity which sacrifices some of its speed, being the AMX-13-90, which is unaffected to the changes. So, there are barely any reason or none at all to raise the EBR '63 to 8.0
Third is about the T20, which is baffling that its being raised considering that we have many 90mm M3 Cannons that are below it. Its armor doesn’t really matter too, considering most of its adversaries have good enough cannons to penetrate frontally just fine. I fail to see how it needs any raise at all to 6.3 when people can just use the T25, which is pretty much an upgrade already sitting at the same BR compared to the T20 if the change is live.
Another is Strela. I fail to see how it’s not 10.0 at the minimum considering that even the Tan-SAM was raised a whole 1.0 BR for most likely the same reason Strela is raised. Especially, in addition to the fact that the Strela is even far more convenient and better to use than many of the 10.3 SAMs thanks to the nerf to SACLOS based SAMs on how it works, especially against faster aircrafts.
As for the rest of changes, they’re generally acceptable, with only few minor things that’s a problem. Like Type 99, which is quite ridiculous to be 7.0 from the get-go with its impressive muzzle velocity and reload for a 155mm SPH.
I understand why the French SPAAs (AMX-13 DCA 40, TPK 6.41 and AMX-10P) are raised, as all of them have very good armament for SPAA work, but I do need to remind the dev team here that the entire reason these were added was to give the French more SPAAs that are spread out through its BR ranges and NOT crowd them to a specific BR range, which it does if this changes went live. My advice is to delay it until there are more SPAA for them available to add, especially for anything right after the CCKW 353 and after AMX-10P.
Lastly is just the AMX-13 (FL11). I don’t understand the fixation of trying to raise it even higher when the M24 Chaffee is untouched, and that thing is technically a better version of it, especially with the M24 having stabilizer. It also doesn’t have the mobility edge that the EBR '51 has that helps it able to use the gun well since it lacks penetration power. That’s all for my complaints for Ground.
Let’s go to Aviation:
I don’t need to talk about much, apart from the Mirage 2000. Both of the Mirage 2000 at its current BR is already quite lacking apart from its Radar, and to some degree, its mobility. In the context of Air Battles, it is extremely lacking compared to its adversaries with it having only 4 missiles max. Not only that, the Missiles in question is also lacking compared to what most of the current top tier has. Super Matra 530D is not as good as the AIM-7F/M and even worse compared to R-27R/ER, only beating the older missiles like Skyflashes and the Magic 2, even being an IR Missile with IRCCM, is lacking compared to other missiles like R-73, AIM-9M and AAM-3 in terms of flare resistance and range. Now, I did say specifically that its mobility is “to some degree” is good, but the problem is that many vehicle by that BR range all has that, especially its other Delta Wing adversary being the JAS 39 A/C, so it even lacks at that regard. So, with those in mind, it’s completely unnecessary to raise the BR of the Mirage 2000C-S5/S4 and Mirage 2000-5F unless they have better Anti-Aircraft Armaments.
Apart from that, I am happy with the decompression for Top Tier Air. I also have nothing to say for Naval as with how little changes are there.
