It is certainly viable on Medium and Hard. That was the actual compo I used in E2H after all. In day time, those secondary boss killers are only good for chipping, don't expect them to deal more than 50 damage to boss outside yasen as I pointed out in the Load outs section.

So in daytime, those DDs, along with support and airstrike are meant to take out the PT imps while the CA, the CVL do the real damage to three big targets. A critical strike from 2-slot CVL can do upward 100 damage to DJ-hime and 150 damage to Artillery imp (parallel and T-green required). The DA from your CA can daytime kill any of the escort and since you get 2 shelling phases (courtesy of the artillery imp), you get 4x devastating blows in daytime from those two ships alone. Worst-case scenario and the CVL gets chuuha, you get 2 from the CA.

In contrast, using the 2CAV setup, you get 0 devastating blow in daytime due to the lack of AS, you get 4 lame attacks instead. I personally would take 2 strong hits than 4 useless hits and I would take early firepower than late firepower.

I can only provide the comp and the reason why I did what I did. There're no auto-win comps, there're only comps that give you a better winning chance. The rest is still up to your luck.
