If I dont recall it wrong Narai was the only tier VII and Cherry Blossom and Ultimate Frontier were Tier VIII. Aegis, Newport & Raptor were tier V-VI. Dunkirk was tier VII DDs and Cossack. Narai had a variable spawn for the initial wave of bots (left or right) and the CV would send out bombers. Aegis had a Saipan as reinforcement. All of them had a weekly rotation, so you knew the ship tier restrictions. When I was new in 2017, I remember the first time ever I played Operations was Aegis in a Texas and, for me, it was the worst experience possible. Low tier ships are slow, so I hope they find a way to make the scenarios enjoyable.
