^The problem isn't the proc rate, it's the despair that comes with the realization that even if you beat the odd and managed to proc your AACI, you're still only shooting down 2~3 bombers per slots. Contrast that with the 8 bombers per slot shot down by Maya, who is still able to DA at night.

Even though installation makes high luck DD not as valuable, it's important to bear in mind that newer players will have no WG42 at their disposal (heck, the Yuu farm map last event is even locked behind an installation boss). This makes the few FP you gained from leveling Yuudachi/Shimakaze to be pointless, because DD just can't do anything to installation bosses. Heck, I would even argue that it's even better to have lower FP so that you'll proc scratch damage rather than magically scoring a 1 damage crit to the boss.

Given the point above, I reckon it's more important to gather high luck DDs. You can switch between DA and Torp CI setup depending on whether there's any non-installation meat shield at the boss node. The correct way to deal with installation for newer players, is to level their Ise-class and Mogami-class and pray for the best with their Type 3 shells.
