It's hard because you have to endure multiple battle in a sortie. by the 3rd or 4th battle, some of your ship may had become moderately damaged and need to return to base (unless you were ready to sacrifice some ship). some said you could clear it easily with submarine alone. no, E4 is even harder. To describe it, imagine you have to sortie 2-4 ten times in a day while your battleships always be heavily damaged. due to the difficulty some admiral were already hoarding 1k bucket and at least 20k resources.
