AACI will become vital for the upcoming event. Type 94 stat is higher than 91 and can be improve to the Gun version with better stat while Type 91 is lower stat and need to upgrade to Type 94 before going to Gun. It's your decision on which way to go for or if you need another high level DD or not. I want to say yet but I don't know much about your situation.

Ship type depends on you yourself. For this event I say 4 of each class will be very useful (except CLT since there's only 3 and CAV since they're hard to get) to avoid getting ship-locked if they show up. I think 3 CV and 3 CVL are a good point. You can decide yourself wheter you want to level ship higher, try crafting more ship or sortie for drops.

Other than that the guide pretty much went into high detail of what to do.
