The problem with the Luch is it is simply too good. T-70 and Stuart have been purposely tone down the last patch but the Luch has only been re-positioned to be less of a dive machine. So we end today with a Luch that rape infantry even from far range and is far too durable vs T-70 and Stuart.
T-70 and Stuart are, at maximum, there to deny an area to the Luch but they can't kill it on their own.
And people telling you the Luch cost the same price than Stuart are simply lying to you. They purposely forget to add the ambulance and Zook/BARs unlock price on the bill, even to be fair in term of unlocked option, we could argue that as USF you still can't use grenade while the OKW can, so it is a 25 fuel upgrade to add...
Sturmpio can produce healing crates from T0
OKW truck = 15 fuel, unlock faust
OKW Mechanized regiment = 50 fuel, unlock STG and lavanade
Luch = 60 Fuel
OKW total fuel spent to reach a Luch = 125
USF Ambulance = 10 fuel
USF Rack = 15 fuel
Captain = 60 fuel
Stuart = 70 fuel
Grenade = 25 fuel
USF total fuel spent for the same amount of option to reach the Stuart = 180
Don't need grenades. Get a mortar instead. I avoid the stuart all together. Simply not worth to counter 1 luchs. Just go zooks and try and hold till m10. This issue isn't so much with the luchs, it's more of the meta which shapes very well for the luchs. USF doesn't go captain mainly anymore because there isn't really anything of value, therefore they don't have an AT gun. Same goes for soviets. No T2 no zis. The luchs would be no issue if conscripts were good and T2 maxims were decent.
