Ok so apart from you getting tanks and basic information such as the type 61 having an autoloader and the m4a1 fl10 having a 10 rnd readyrack, most of these suggestions are horrifying. The t92 bounces if you can’t aim. The t30 is a worse, not better, t34. The m50 is completely fine at 6.7 but counters stupid and blind players. However, I agree with the t34, t26e5, m551 and t29 going up.
The 2 tigers should not go up, while they are better they still have the intrinsic tiger H weakness. The tiger 2 105 is worse or at best on par with the kth. The luchs is already fine to mediocre at 7.3. The rest are fine. The gepard can maybe go to 8.7 but 9.0 is too much of a stretch. The begleit is also fine where it is. The kv1 is one of the best 4.7 tanks and absolutely should not go down. The finnish one should go back up to 5.0 where it was already good.
The IS-3 should never face 6.0 tanks. The IS-6 and t54’s going down is a joke because these are already good enough and well balanced at their respective brs. The rest seem fine but a the t80s could move up after the buff.
The fox counters blind and deaf players, the conqueror is mediocre at 7.7 and the za can go up.
The sta3 (this is the one with an autoloader) and type 61 are completely fine where they are. The ho ri prototype is not that good of a tank vs anyone that has a clue of where to shoot it. The production is good at 7.3 but not 7.7 worthy, same situation as the prototype. The type 60 sprg is a MUCH worse m50, and the type 99 could go up.
The obj 122 can go up, but the aft, once again, is not that good.
The dardo going down to 9.7 is absurd, it is completely fine at 10.0. the aubl buff without at least a 2-step increase in br is nuts.
The amx50 to90 is at 8.0 for a VERY good reason. It has almost double the other fast french mediums’ readyrack size, with their speed, reload and great aphe. It should absolutely NOT go down. The m4a1 fl10 is good at 5.0 but not incredible, due to poor depression, armour, mediocre mobility and a shell that is not particularly reliable in terms of damage.
The bkan is completely fine at 6.7, it’s not a particularly good vehicle. The ush is also fine, while the pbv could go up but it is not necessary to move it up as it is very easily counterable. The itpsv could go up to 9.0.
Overall this seems like a very knee-jerk reaction to vehicles that you either did not do well in when playing, struggle facing or just simply do not have a lot of actual experience with. I do suggest getting more experience, maybe look at a few guides or good streamers to start improving your gameplay a little.
