Let’s start with the French Tech Tree; this is how it looks like now with its new 7 tanks:
Note: There was no players queuing for low tier battles as usual, I was only able to have matches with the Renault G1, AMX 30 1st Prototype and the AMX 30 B.
-Research cost: 50
-Purchase price: 3,900
Seems decent, has the same armor values as the "Mini-Maus" Pz 38H except for the sides and back of the hull which is pretty nice and its gun has one of the best tier II penetration/damage values BUT don't except to go anywhere fast with it, only 24 km/h as top speed.
-Research cost: 70
-Purchase price: 3,850
It has same gun as the FCM 36 but has more view/signal range and side hull armor which makes it even slower, 23 km/h.
-Medium Tank (?)
-Research cost: 1,360
-Purchase price: 42,000
Nothing really special about its gun and the entire armor is not much stronger than the Renault R35 but its tier V engine brings a huge boost as it reaches 45 km/h as top speed, it also has a tremendously good signal range.
-Research cost: 3,230
-Purchase price: 155,000
Its gun is actually pretty good on both penetration and damage values and also has a very good signal range, its speed although is slower than the Somua S35, still okay but the armor is just depressing.
-Research cost: 13,550
-Purchase price: 350,000
This tank has a 105mm derp and a 75mm non-derp gun options, both of them are actually quite decent in comparison with other mediums of same tier but I personally like the 105mm derp (Jingles has corrupted me), if your speed hasn't improved from the SARL 42 and the armor sucks might as well have some dirty fun right?
AMX 30 1st prototype
-Research cost: 197,000
-Purchase price: 3,550,000
Time for the big boys. This tank is quite good, it may have poor armor but it just increases the mobility and acceleration that is very nice (even on reverse) and you can easily relocate to better positions and evade the enemy. On its gun, the penetration and damage values are pretty decent and found it to be quite accurate, the aiming time is a bit mediocre but it can be easily fixed with a Enhanced Gun Laying Drive, make sure to put Vertical Stabilizer Mk 1 as you will require to fire on the move frequently.
AMX 30 B
-Research cost: 180,100
-Purchase price: 6,100,000
And finally but definitely, so definitely not least, the AMX 30B; It has the same speed/mobility as his predecessor but has more hit points, sightly extra armor, view range, faster turret and traverse speed and the best, it reloads more rapidly! Loved it even more than the AMX 30 1st prototype!
A summary for both AMX's: When I saw the models for the first time their size, which is the same, and commander hatches worried me but this tanks have great gun elevation and depression, make sure to use it as an advantage together with their mobility and you will do fine, oh, and derp guns, avoid getting hit by them especially!
