Luchs 2cm accuracy: 0.775/0.65/0.56
222 2cm accuracy vs inf: 0.56/0.36/0.27
222 2cm vs vehicles: 0.06/0.04/0.03
Of course, 222 2cm has better moving accuracy and has accuracy bouses at vet but the MG is still the main source of damage for the 222 against infantry. Also It is more costly at 260manpower/35 fuel.
The MG is the main source of AI right now, but I don't think it will be after this buff. I know the 2cm is quite shit against infantry at the moment, but increasing its accuracy against infantry by 900% means a straight up 2cm DPS increase of 900%. So it'll have that damage along with the MG that I believe you're also buffing a little.
I'm not against the 222 getting buffed, but all of this for 35 fuel is ridiculous. It's too low. You're creating a lighter armored, but faster Luchs for half its fuel cost. And even though its armor is going to be lighter, it's still going to require dedicated AT to handle it because you're buffing its armor as well to the point where small arms will barely do anything.
