Why shouldn't there be overlap between weapon types? Personally the high rate of fire scouts and low-medium fire rate autos are my favorite guns to use, and allowing each type to have outliers that bridge the gap to a different weapon type only gives players more fun and more options. I think the high fire rate ars should have way more impact, slightly smaller magazines, and recoil bad enough to make long distance engagements have long TTKs just because of accuracy, while making them close range chainsaws.
