Mp 10 is better than mp 01 in every single way well at least to me I don't mind the smaller size and lack of die cast compared to mp 01. Keep mp 10 the way it is because adding obsolete mp 01 designs to a modern mp is a step back and will make it worse.
I do like the MP1 chest. It's not as round as MP10. As for vehicle mode, MP10 was perfect. So, how would a hybrid of MP1 and 10 look?
