The high accuracy is supposed to help it maintain DPS while moving though, isnt it? Combined with the generic USF superior moving accuracy. I get the impression its supposed to be more "Hit and run" than "Brawler"
The Easy Eight is already kinda accurate on itself because of low scatter.
Consider the 76mm has 150 far penetration and 3.26 second reload at vet 3, while a vet 3 Easy Eight has 155 far penetration but 5.29 second reload, it scales kinda lackluster comparatively. 215 armor also isn't that impressive against AT guns anyway. The extra hp is nice though.
Instead of penetration replacing accuracy, it could instead get a +5 range bonus at vet 2 (not replacing anything). Easy Eight is good when it arrives, but once late game full pop highly vetted armies kick in, you'Il wish you went with something more reliable against armor.
