That's why I'd have its main gun functional so it's not dead weight. Basically I'd have it act like Tulips but an AI barrage instead.
Yoi get so many more ways to tweak then and ensure that it's powerlevel and cost effectiveness is where it's wanted.
I know realism isn't supposed to matter but it in this case it would bother me if they did that. The Sherman's main gun was pretty much useless when the launcher was mounted. There's stories of guys modifying it in the field to work, but the gun was always much less effective
I think using realism to say X should beat Y is dumb, but when it comes to whether or not something was even possible, I wish Relic cared a little more about realism
