Greetings everyone, I was wondering as a newbie player; should I focus on getting tier7 hiryu and skip the HE bomber upgrade on Ryujo - I will be going to get 1-2-2 loadout- or should I upgrade everything? As I have seen and read so far, the game for CV's really start from tier7, and below are the path to learn how to play CV. So what are your thoughts on this, Should I upgrade HE bombers for 4200 exp or, focus on getting Hiryu first? Thank you. JustSayinxx
