I agree with this idea.
GVs are still very, very darn small in the pintle gun view. I've been finding that Panzers, Tigers, Flaks, and the other mottled GVs are reasonably easy to spot in pintle view, but the Shermans and other uniform olive drab GVs are darn near impossible to spot against the MA's uniform drab green terrain, in pintle view. It is a real problem-spotting German tanks vrs. the Shermans. It is like looking for guys in street clothes in the woods vrs. guys in full camo.
You have turret view of course, but with this "binocular" or whatever zoom available on pintle view you could look around with faster rotation without getting your turret all out of alignment.
