Why is the S-38b 1.7?!?

Why would you guys make this thing 1.7?!? It’s awful at this BR, all it really gets that the version before it doesn’t is 2 MG-34s which don’t even help that much! I think it should be 1.3. Like this things at the same br as the OD-200 which is armed with 2 12.7 mm guns and a 37mm Auto cannon! This thing is absolutely not 1.7 material! Please lower it to 1.3!
