E2H = Main problems reaching the boss safely, even with top tier equips the accuracy of DDs are awfully bad for me, they miss 9 out 10 times leaving enemies alive to Taiha with closing torpedo salvos(i hate how their closing torpedo salvo is 100 times more deadly than outs), the number one reason i hate deploying light fleets and rather spend a lot on heavy ones.

It would be a good idea to test out the Air Supor expedition on pre-boss nodes since they are kinda soft and the spread damage maybe can lessen the damage they can incur with closing torpedo salvos.
