A few things from my experience with E5:

1. Never replace Aki-class radar with wurf, not worth it, you will get rekt

(Actually not sure if wurfing is worth it at all, I was trying if Torp cutin setup for Ayanami in second position was better. My theory was clearing the other enemies to let the cruisers use type3 and nuke the boss)

2. Night recon is pretty useless since the only night battle is pretty much always in Air Denial. Although not sure if type 0 obs. is  any better.

3. Seiran, type 3 shell are your best friend in this map

These are my 2 cents about E5, just sharing my experience
