As i recall, issues were not of low ROF and high damage, but of low penetration. U could wait loong time before it fires and bounces of Pz4. And that was trash. But now IS penetration is very reliable. So if we increase damage to 200, and decrease ROF. DPS would be almost the same, but burst damage will be higher, like a heavy tank should have
Low RoF means it's a nerf in the AI department.
If you maintain the same DPS, the 200dmg is a nerf to it's AT performance. Let me put it more clear.
Say rof is 6s (from avg 6.4), so you need to increase rof to 7.5. This is the TTK for most vehicles in game if i didn't skip anything. OR at least anything relevant

Red is worst performance and green the opposite. And this is only with perfect accuracy and penetration. Miss and failed pens would require more shots, therefore making most if not all match ups worst.
