The Camo nerf proves that balance team can be and are complete morons sometimes.
I mean why not just remove camo From grens and JCS.
Balance Team probably the worst thing to happen to the game honestly. The game isn't any more balanced than when they started and if anything it is more imbalanced than before due to power creep.
Now lets create a fake scenario as an example. Take a theoretical situation where Pioneers are under performing vs Combat Engineers. People complain, balance team will go and create a 5th Squad Member upgrade, give it like 100% accuracy at all ranges, Pioneer spam then becomes meta then they get nerfed into a worse position than what they were previously. Instead of saying ok, lets give Pioneers 10% accuracy bonus vs Combat Engineers only, then tweak/modify from there until its balanced.
Good Example of this was Rifleman vs Volks. Rifleman were fine vs Grenadiers but struggled vs OKW, rather than buff the unit against Volksgrenadiers only, they fixed the Volksgrenadier issue only to make Rifleman overperform vs Grenadiers creating another balance issue in the process.
There are 5 factions in the game so any change to one thing could have a profound effect on how that interacts with numerous other units. This is why they need to stop doing generic changes that effects how units interact with every other unit in the game and go for a more surgical approach. Think of it like a ripple effect in a pond. Rather than do generic changes that are very specific to what the issue is, they do massive sweeping generic changes.
Look at UKF for example. Pre-Nerf Infantry Sections only needed some tweaks, mostly in the form of doing less damage vs MGs. (All LMGs should have a damage penalty vs Heavy Machine Guns to prevent frontal attack move assaults but that is another topic) Being able to get Double Bren then Max Range demolish MGs was the main problem as you had no way to control blobbing. Instead of fixing that, Infantry Sections went through a balance loop of endless nerf after nerf until they became so garbage that they had to introduce Raid Sections into the game which will further upset balance even more.
Raid Sections wouldn't be needed if Infantry Sections weren't gutted into the ground but here we are. In a month something else will be considered OP and then nerfed into the ground and the never ending cycle continues since they don't address problems in a way that actually fixes things permanently.
