Vehicle Rebalancing:

Along with a host of other changes, there will be a rebalancing of a fairly large number of tanks with the 7.5 update.
Tier 2-3 Tank Destoyers:
Most of these changes stem from the fact that the match maker has been adjusted to give tighter tier spreads for most tanks. The tier II & III tank destroyers would be massively overpowered in these match-ups if there were no adjustments.

Economy:

Changes to the in-game economy started with the v. 0.7.2 update and will be continued in the v. 0.7.5 update.
First of all, some of the Tier 2-4 vehicles will get an increase to their profitability. The speed of leveling through these tiers doesn't match the new concept. Players were able to earn the amount of experience necessary to research new vehicles quite fast, but they had a problem getting enough credits, so they had to farm credits over a much longer period of time. This trouble has been resolved by increasing profitability and decreasing repair costs.
Some of the US Tier 6-7 medium tanks are much better situated when compared with their counterparts from other nations. For example, the Sherman Jumbo and M4A3E8 Sherman have a very low repair cost and a fairly high profit potential. This allows them to often finish matches with a greater net gain of credits than VK 3601. We wanted to correct this imbalance. M26 Pershing players should be delighted to learn that their repair costs are being significantly reduced.
The second branch of US Tier 5-8 Tank Destroyers, introduced with the v. 0.7.2 update, are more profitable than was originally intended. This is mostly due to the exceptional combat characteristics of these vehicles. This branch earns significantly more credits when compared to the original branch (ending in the T95). This imbalance will be fixed in the v. 0.7.5 update.
The economic model of German vehicles of Tier 7-8 will be changed as well. Players who have Jagdpanther and VK3002 (DB) will be happy to hear that we're decreasing their repair costs. At the same time, the Tiger (P) will get the same profit potential rate as the other representatives of “Tiger” family made by Henschel. Also, we have good news for those who have a Löwe in the Garage, we're increasing the profit potential and reducing the repair costs.
The M6A2E1 is also due for a credit increase and repair cost reduction.
The profiti potential for the Jagdtiger and Object 704 tank destroyers will be slightly lessened. They will earn slightly less credits so that their earnings are more in line with the other tier 9 tank destroyers.
In addition to the Object 704 getting an adustment, the KV-3 having been moved in the v. 0.7.3 update to Tier 7, turned out to have too high of a repair cost; this will be decreased. Profitability for the IS-3 is a bit higher compared to the other tier 8 heavies. We'll be adjusting the profit potential for this tank with the v 0.7.5 update as well.

French Tree Changes:

With the 7.5 addition of a few new tanks the French Tech Tree is in need of some rearranging.
With the addition of the ELC AMX, the АМХ 12t is going to be moved up to Tier 6. Its place at tier 5 in the Tech tree will be taken over by the ELC AMX.
Case 1. AMX 12t isn’t in the garage at the time of the update release, but is fully researched:

Both tanks, ELC AMX and AMX 12t, will be researched
All undistributed experience goes from AMX 12t will be moved to the ELC AMX
Any crew member in the barracks or in a tank, who possesses the tier 5 AMX 12t skills, get the ability to be used in the tier 6 AMX 12t without any changes or losses
Tier 5 AMX 12t combat statistics will be moved to the tier 5 AMX 12t without any losses
All AMX 12t modules in the depot that don’t fit other tanks will be automatically sold at the original purchase price
All AMX 12t modules fitting other tanks will be saved in the depot, the same goes for shells of the respective guns

Case 2. AMX 12t is in the garage at the time of the update release. All the rules as mentioned in Case 1 apply along with the following:

AMX 12t as tier 5 light tank is substituted with AMX 12t as tier 6 light tank
Ammunition mounted onto the AMX 12t goes to the depot
Consumables and Equipment mounted onto the tier 5 AMX 12t remain on AMX 12t at tier 6.
Players get the light french Tier 5 tank ELC AMX (without equipment, consumables, ammunition) and one slot for this tank for free
Players get a new full crew for the ELC AMX with 100% training
Camouflage mounted onto the Tier 5 AMX 12t is moved to tier 6 AMX 12t and to ELC AMX as well
The expiration date of the camo on both vehicles stays the same as it was for the AMX 12t at the moment when the substitution takes place.

AMX 13 75 is going to be moved up to Tier 7
АМХ 13 90 is going to be moved up to Tier 8

Suspensions in depot are sold at original purchase price and credits go to player’s account
Gun 105mm CN 105 57 will be mounted onto the tank only if the Gun 100 mm SA 47 was researched and mounted onto the tank
If There was a Gun 90 mm DCA 45 mounted onto the tank the shells for it go to the depot and the gun will be replaced with the Gun 90mm F3
