The M20 is not as shocking and game breaking as the Stuart, which is available 5 minutes in game and is supported by CPT. It can sometimes one shot axis units, has a crush similar to mediums, the critical ability shocks other vehicles and it takes 3 and some times 4 (OKW AT) AT shots to die.
This definitely shouldn't be the case with a "light support" vehicles. While ostheer has no counter aside from their support (Pak, Shreck) which shouldn't be so in competitive RTS, OKW can't afford a puma that early either and it is ALWAYS a bad investment; low health and no AI.
It is so over performing that most players have just abandoned the shermans and build a stuart and wait for callins.
Please reduce the health and give it a defined role, AI or AT.
Are you serious? The Stuart is not a good unit at all. It's AI is terrible compared to the T-70 which is amazing. It DOES NOT have crush at all. and its damage is poop with its normal cannon. This unit barely hits infantry units and fires slowly.
PUMA and panzer 4 rape this unit. Shreck blobs kill this unit. Mines one shot this unit. Paks stop it.
Stuart is more of a keep on a flank and defend a point unit or stun a unit so zooks or AT can grab it.
